1openssh (1:7.9p1-1) unstable; urgency=medium
2
3 OpenSSH 7.9 includes a number of changes that may affect existing
4 configurations:
5
6 * ssh(1), sshd(8): the setting of the new CASignatureAlgorithms option
7 bans the use of DSA keys as certificate authorities.
8 * sshd(8): the authentication success/failure log message has changed
9 format slightly. It now includes the certificate fingerprint
10 (previously it included only key ID and CA key fingerprint).

14openssh (1:7.8p1-1) unstable; urgency=medium
15
16 OpenSSH 7.8 includes a number of changes that may affect existing
17 configurations:
18
19 * ssh-keygen(1): Write OpenSSH format private keys by default instead of
20 using OpenSSL's PEM format. The OpenSSH format, supported in OpenSSH
21 releases since 2014 and described in the PROTOCOL.key file in the
22 source distribution, offers substantially better protection against
23 offline password guessing and supports key comments in private keys.
24 If necessary, it is possible to write old PEM-style keys by adding "-m
25 PEM" to ssh-keygen's arguments when generating or updating a key.
26 * sshd(8): Remove internal support for S/Key multiple factor
27 authentication. S/Key may still be used via PAM or BSD auth.
28 * ssh(1): Remove vestigial support for running ssh(1) as setuid. This
29 used to be required for hostbased authentication and the (long gone)
30 rhosts-style authentication, but has not been necessary for a long
31 time. Attempting to execute ssh as a setuid binary, or with uid !=
32 effective uid will now yield a fatal error at runtime.
33 * sshd(8): The semantics of PubkeyAcceptedKeyTypes and the similar
34 HostbasedAcceptedKeyTypes options have changed. These now specify
35 signature algorithms that are accepted for their respective
36 authentication mechanism, where previously they specified accepted key
37 types. This distinction matters when using the RSA/SHA2 signature
38 algorithms "rsa-sha2-256", "rsa-sha2-512" and their certificate
39 counterparts. Configurations that override these options but omit
40 these algorithm names may cause unexpected authentication failures (no
41 action is required for configurations that accept the default for these
42 options).
43 * sshd(8): The precedence of session environment variables has changed.
44 ~/.ssh/environment and environment="..." options in authorized_keys
45 files can no longer override SSH_* variables set implicitly by sshd.
46 * ssh(1)/sshd(8): The default IPQoS used by ssh/sshd has changed. They
47 will now use DSCP AF21 for interactive traffic and CS1 for bulk. For a
48 detailed rationale, please see the commit message:

54
55 OpenSSH 7.6 includes a number of changes that may affect existing
56 configurations:
57
58 * ssh(1): Delete SSH protocol version 1 support, associated configuration
59 options and documentation.
60 * ssh(1)/sshd(8): Remove support for the hmac-ripemd160 MAC.
61 * ssh(1)/sshd(8): Remove support for the arcfour, blowfish and CAST
62 ciphers.
63 * Refuse RSA keys <1024 bits in length and improve reporting for keys
64 that do not meet this requirement.
65 * ssh(1): Do not offer CBC ciphers by default.

70
71 OpenSSH 7.5 includes a number of changes that may affect existing
72 configurations:
73
74 * This release deprecates the sshd_config UsePrivilegeSeparation option,
75 thereby making privilege separation mandatory.
76
77 * The format of several log messages emitted by the packet code has
78 changed to include additional information about the user and their
79 authentication state. Software that monitors ssh/sshd logs may need to
80 account for these changes. For example:
81
82 Connection closed by user x 1.1.1.1 port 1234 [preauth]
83 Connection closed by authenticating user x 10.1.1.1 port 1234 [preauth]
84 Connection closed by invalid user x 1.1.1.1 port 1234 [preauth]
85
86 Affected messages include connection closure, timeout, remote
87 disconnection, negotiation failure and some other fatal messages
88 generated by the packet code.

92openssh (1:7.4p1-7) unstable; urgency=medium
93
94 This version restores the default for AuthorizedKeysFile to search both
95 ~/.ssh/authorized_keys and ~/.ssh/authorized_keys2, as was the case in
96 Debian configurations before 1:7.4p1-1. Upstream intends to phase out
97 searching ~/.ssh/authorized_keys2 by default, so you should ensure that
98 you are only using ~/.ssh/authorized_keys, at least for critical
99 administrative access; do not assume that the current default will remain
100 in place forever.

105
106 OpenSSH 7.4 includes a number of changes that may affect existing
107 configurations:
108
109 * ssh(1): Remove 3des-cbc from the client's default proposal. 64-bit
110 block ciphers are not safe in 2016 and we don't want to wait until
111 attacks like SWEET32 are extended to SSH. As 3des-cbc was the only
112 mandatory cipher in the SSH RFCs, this may cause problems connecting to
113 older devices using the default configuration, but it's highly likely
114 that such devices already need explicit configuration for key exchange
115 and hostkey algorithms already anyway.
116 * sshd(8): Remove support for pre-authentication compression. Doing
117 compression early in the protocol probably seemed reasonable in the
118 1990s, but today it's clearly a bad idea in terms of both cryptography
119 (cf. multiple compression oracle attacks in TLS) and attack surface.
120 Pre-auth compression support has been disabled by default for >10
121 years. Support remains in the client.
122 * ssh-agent will refuse to load PKCS#11 modules outside a whitelist of
123 trusted paths by default. The path whitelist may be specified at
124 run-time.
125 * sshd(8): When a forced-command appears in both a certificate and an
126 authorized keys/principals command= restriction, sshd will now refuse
127 to accept the certificate unless they are identical. The previous
128 (documented) behaviour of having the certificate forced-command
129 override the other could be a bit confusing and error-prone.
130 * sshd(8): Remove the UseLogin configuration directive and support for
131 having /bin/login manage login sessions.
132
133 The unprivileged sshd process that deals with pre-authentication network
134 traffic is now subject to additional sandboxing restrictions by default:
135 that is, the default sshd_config now sets UsePrivilegeSeparation to
136 "sandbox" rather than "yes". This has been the case upstream for a while,
137 but until now the Debian configuration diverged unnecessarily.

143 OpenSSH 7.2 disables a number of legacy cryptographic algorithms by
144 default in ssh:
145
146 * Several ciphers blowfish-cbc, cast128-cbc, all arcfour variants and the
147 rijndael-cbc aliases for AES.
148 * MD5-based and truncated HMAC algorithms.
149
150 These algorithms are already disabled by default in sshd.

155
156 OpenSSH 7.0 disables several pieces of weak, legacy, and/or unsafe
157 cryptography.
158
159 * Support for the legacy SSH version 1 protocol is disabled by default at
160 compile time. Note that this also means that the Cipher keyword in
161 ssh_config(5) is effectively no longer usable; use Ciphers instead for
162 protocol 2. The openssh-client-ssh1 package includes "ssh1", "scp1",
163 and "ssh-keygen1" binaries which you can use if you have no alternative
164 way to connect to an outdated SSH1-only server; please contact the
165 server administrator or system vendor in such cases and ask them to
166 upgrade.
167 * Support for the 1024-bit diffie-hellman-group1-sha1 key exchange is
168 disabled by default at run-time. It may be re-enabled using the
169 instructions at http://www.openssh.com/legacy.html
170 * Support for ssh-dss, ssh-dss-cert-* host and user keys is disabled by
171 default at run-time. These may be re-enabled using the instructions at
172 http://www.openssh.com/legacy.html
173 * Support for the legacy v00 cert format has been removed.
174
175 Future releases will retire more legacy cryptography, including:
176
177 * Refusing all RSA keys smaller than 1024 bits (the current minimum is
178 768 bits).
179 * Several ciphers will be disabled by default: blowfish-cbc, cast128-cbc,
180 all arcfour variants, and the rijndael-cbc aliases for AES.
181 * MD5-based HMAC algorithms will be disabled by default.

195 openssh-server 1:6.7p1-4 changed the default setting of AcceptEnv to list
196 a number of specific LC_FOO variables rather than the wildcard LC_*. I
197 have since been persuaded that this was a bad idea and have reverted it,
198 but it is difficult to automatically undo the change to
199 /etc/ssh/sshd_config without compounding the problem (that of modifying
200 configuration that some users did not want to be modified) further. Most
201 users who upgraded via version 1:6.7p1-4 should restore the previous value
202 of "AcceptEnv LANG LC_*" in /etc/ssh/sshd_config.

208 Smartcard support is now available using PKCS#11 tokens. If you were
209 previously using an unofficial build of Debian's OpenSSH package with
210 OpenSC-based smartcard support added, then note that commands like

217
218 The ssh package has been split into openssh-client and openssh-server. If
219 you had previously requested that the sshd server should not be run, then
220 that request will still be honoured. However, the recommended approach is
221 now to remove the openssh-server package if you do not want to run sshd.
222 You can remove the old /etc/ssh/sshd_not_to_be_run marker file after doing
223 that.

228
229 This version of OpenSSH disables the environment option for public keys by
230 default, in order to avoid certain attacks (for example, LD_PRELOAD). If
231 you are using this option in an authorized_keys file, beware that the keys
232 in question will no longer work until the option is removed.
233
234 To re-enable this option, set "PermitUserEnvironment yes" in
235 /etc/ssh/sshd_config after the upgrade is complete, taking note of the
236 warning in the sshd_config(5) manual page.

242 As of version 3, OpenSSH no longer uses separate files for ssh1 and ssh2

244 needed. They will still be read in order to maintain backward
245 compatibility.

10As of 1:6.6p1-1, new installations will be set to "PermitRootLogin
11without-password" (or the synonymous "PermitRootLogin prohibit-password" as
12of 1:7.1p1-1). This disables password authentication for root, foiling
13password dictionary attacks on the root user. Some sites may wish to use
14the stronger "PermitRootLogin forced-commands-only" or "PermitRootLogin no",
15but note that "PermitRootLogin no" will break setups that SSH to root with a
16forced command to take full-system backups. You can use PermitRootLogin in
17a Match block if you want finer-grained control here.
18
19For many years Debian's OpenSSH packaging used "PermitRootLogin yes", in
20line with upstream. To avoid breaking local setups, this is still true for
21installations upgraded from before 1:6.6p1-1. If you wish to change this,
22you should edit /etc/ssh/sshd_config, change it manually, and run "service
23ssh restart" as root.
24
25Disabling PermitRootLogin means that an attacker possessing credentials for
26the root account (any credentials in the case of "yes", or private key
27material in the case of "prohibit-password") must compromise a normal user
28account rather than being able to SSH directly to root. Be careful to avoid
29a false illusion of security if you change this setting; any account you
30escalate to root from should be considered equivalent to root for the
31purposes of security against external attack. You might for example disable
32it if you know you will only ever log in as root from the physical console.
33
34Since the root account does not generally have non-password credentials
35unless you explicitly install an SSH public key in its
36~/.ssh/authorized_keys, which you presumably only do if you want to SSH to
37it, "prohibit-password" should be a reasonable default for most sites.
38
39As of OpenSSH 7.0, this is the upstream default.

46X11 Forwarding
47--------------
48
49ssh's default for ForwardX11 has been changed to ``no'' because it has
50been pointed out that logging into remote systems administered by
51untrusted people is likely to open you up to X11 attacks, so you
52should have to actively decide that you trust the remote machine's
53root, before enabling X11. I strongly recommend that you do this on a
54machine-by-machine basis, rather than just enabling it in the default
55host settings.
56
57In order for X11 forwarding to work, you need to install xauth on the
58server. In Debian this is in the xbase-clients package.
59
60As of OpenSSH 3.1, the remote $DISPLAY uses localhost by default to reduce
61the security risks of X11 forwarding. Look up X11UseLocalhost in
62sshd_config(8) if this is a problem.
63
64OpenSSH 3.8 invented ForwardX11Trusted, which when set to no causes the
65ssh client to create an untrusted X cookie so that attacks on the
66forwarded X11 connection can't become attacks on X clients on the remote
67machine. However, this has some problems in implementation - notably a
68very short timeout of the untrusted cookie - breaks large numbers of
69existing setups, and generally seems immature. The Debian package
70therefore sets the default for this option to "yes" (in ssh itself,
71rather than in ssh_config).
72
73Fallback to RSH
74---------------
75
76The default for this setting has been changed from Yes to No, for
77security reasons, and to stop the delay attempting to rsh to machines
78that don't offer the service. Simply switch it back on in either
79/etc/ssh/ssh_config or ~/.ssh/config for those machines that you need
80it for.
81
82Setgid ssh-agent and environment variables
83------------------------------------------
84
85As of version 1:3.5p1-1, ssh-agent is installed setgid to prevent ptrace()
86attacks retrieving private key material. This has the side-effect of causing
87glibc to remove certain environment variables which might have security
88implications for set-id programs, including LD_PRELOAD, LD_LIBRARY_PATH, and
89TMPDIR.
90
91If you need to set any of these environment variables, you will need to do
92so in the program exec()ed by ssh-agent. This may involve creating a small
93wrapper script.
94
95Symlink Hostname invocation
96---------------------------
97
98This version of ssh no longer includes support for invoking ssh with the
99hostname as the name of the file run. People wanting this support should
100use the ssh-argv0 script.
101
102=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
103
104OTHER ISSUES
105============
106
107Authorization Forwarding
108------------------------
109
110Similarly, root on a remote server could make use of your ssh-agent
111(while you're logged into their machine) to obtain access to machines
112which trust your keys. This feature is therefore disabled by default.
113You should only re-enable it for those hosts (in your ~/.ssh/config or
114/etc/ssh/ssh_config) where you are confident that the remote machine
115is not a threat.
116
117Problems logging in with RSA authentication
118-------------------------------------------
119
120If you have trouble logging in with RSA authentication then the
121problem is probably caused by the fact that you have your home
122directory writable by group, as well as user (this is the default on
123Debian systems).
124
125Depending upon other settings on your system (i.e. other users being
126in your group) this could open a security hole, so you will need to
127make your home directory writable only by yourself. Run this command,
128as yourself:
129
130 chmod g-w ~/
131
132to remove group write permissions. If you use ssh-copy-id to install your
133keys, it does this for you.
134
135-L option of ssh nonfree
136------------------------
137
138non-free ssh supported the usage of the option -L to use a non privileged
139port for scp. This option will not be supported by scp from openssh.
140
141Please use instead scp -o "UsePrivilegedPort=no" as documented in the
142manpage to scp itself.
143
144Problem logging in because of TCP-Wrappers
145------------------------------------------
146
147ssh is compiled with support for tcp-wrappers. So if you can no longer
148log into your system, please check that /etc/hosts.allow and /etc/hosts.deny
149are configured so that ssh is not blocked.
150
151Kerberos support
152----------------
153
154ssh is now compiled with Kerberos support. Unfortunately, privilege
155separation is incompatible with parts of Kerberos support for protocol 2;
156you may need to run kinit after logging in.
157
158Interoperability between scp and the ssh.com SSH server
159-------------------------------------------------------
160
161In version 2 and greater of the commercial SSH server produced by SSH
162Communications Security, scp was changed to use SFTP (SSH2's file transfer
163protocol) instead of the traditional rcp-over-ssh, thereby breaking
164compatibility. The OpenSSH developers regard this as a bug in the ssh.com
165server, and do not currently intend to change OpenSSH's scp to match.
166
167Workarounds for this problem are to install scp1 on the server (scp2 will
168fall back to it), to use sftp, or to use some other transfer mechanism such
169as rsync-over-ssh or tar-over-ssh.
170
171Running sshd from inittab
172-------------------------
173
174Some people find it useful to run the sshd server from inittab, to make sure
175that it always stays running. To do this, stop sshd ('service ssh stop'),
176add the following line to /etc/inittab, and run 'telinit q':
177
178 ss:2345:respawn:/usr/sbin/sshd -D
179
180If you do this, note that you will need to stop sshd being started in the
181normal way ('update-rc.d ssh disable') and that you will need to restart
182this sshd manually on upgrades.
183
184Per-connection sshd instances with systemd
185------------------------------------------
186
187If you want to reconfigure systemd to listen on port 22 itself and launch an
188instance of sshd for each connection (inetd-style socket activation), then
189you can run:
190
191 systemctl stop ssh.service
192 systemctl start ssh.socket
193
194To make this permanent:
195
196 systemctl disable ssh.service
197 systemctl enable ssh.socket
198
199This may be appropriate in environments where minimal footprint is critical
200(e.g. cloud guests). Be aware that this bypasses MaxStartups, and systemd's
201MaxConnections cannot quite replace this as it cannot distinguish between
202authenticated and unauthenticated connections; see
203https://bugzilla.redhat.com/show_bug.cgi?id=963268 for more discussion.
204
205The provided ssh.socket unit file sets ListenStream=22. If you need to have
206it listen on a different address or port, then you will need to do this as
207follows (modifying ListenStream to match your requirements):
208
209 mkdir -p /etc/systemd/system/ssh.socket.d
210 cat >/etc/systemd/system/ssh.socket.d/listen.conf <<EOF
211 [Socket]
212 ListenStream=2222
213 EOF
214 systemctl daemon-reload
215
216See systemd.socket(5) for details.
217
218Terminating SSH sessions cleanly on shutdown/reboot with systemd
219----------------------------------------------------------------
220
221If you have libpam-systemd >= 230 installed (following openssh-server's
222Recommends) and "UsePAM yes" in sshd_config (the default configuration
223shipped by this package), then SSH sessions will be terminated cleanly when
224the server is shut down or rebooted.
225
226If either of these conditions does not hold, then you may find that SSH
227sessions hang silently when the server is shut down or rebooted. If you do
228not want to use PAM or configure it properly for whatever reason, then you
229can instead copy
230/usr/share/doc/openssh-server/examples/ssh-session-cleanup.service to
231/etc/systemd/system/ and run "systemctl enable ssh-session-cleanup.service".
232
233Non-systemd users may find /usr/lib/openssh/ssh-session-cleanup helpful if
234they have a similar problem, although at present there is no system
235integration for this for anything other than systemd.
236
237SSH protocol 1 server support removed
238-------------------------------------
239
240sshd(8) no longer supports the old SSH protocol 1, so all the configuration
241options related to it are now deprecated and should be removed from
242/etc/ssh/sshd_config. These are:
243
244 KeyRegenerationInterval
245 RSAAuthentication
246 RhostsRSAAuthentication
247 ServerKeyBits
248
249The Protocol option is also no longer needed, although it is silently
250ignored rather than deprecated.
251
252if-up hook removed
253------------------
254
255openssh-server previously shipped an if-up hook that restarted sshd when a
256network interface came up. This generally caused more problems than it
257solved: for instance, it means that sshd stops listening briefly while being
258restarted, which can cause problems in some environments, particularly
259automated tests.
260
261The only known situation where the if-up hook was useful was when
262sshd_config was changed to add ListenAddress entries for particular IP
263addresses, overriding the default of listening on all addresses, and the
264system is one that often roams between networks. In such a situation, it is
265better to remove ListenAddress entries from sshd_config (restoring it to the
266default behaviour) and instead use firewall rules to restrict incoming SSH
267connections to only the desired interfaces or addresses.
268
269For further discussion, see:
270
271 https://bugs.launchpad.net/bugs/1674330
272
273IPQoS defaults reverted to pre-7.8 values
274-----------------------------------------
275
276OpenSSH 7.8 changed the default IPQoS settings to use DSCP AF21 for
277interactive traffic and CS1 for bulk. This caused some problems with other
278software ("iptables -m tos" and VMware), so Debian's OpenSSH reverts this
279change for the time being.
280
281This is *temporary*, and we expect to come back into sync with upstream
282OpenSSH once those other issues have been fixed. If you want to restore the
283upstream default, add this to ssh_config and sshd_config:
284
285 IPQoS af21 cs1

99openssh (1:7.9p1-1) unstable; urgency=medium
100
101 * New upstream release (https://www.openssh.com/txt/release-7.9):
102 - ssh(1), sshd(8): allow most port numbers to be specified using service
103 names from getservbyname(3) (typically /etc/services; closes:
104 #177406).
105 - ssh(1): allow the IdentityAgent configuration directive to accept
106 environment variable names. This supports the use of multiple agent
107 sockets without needing to use fixed paths.
108 - sshd(8): support signalling sessions via the SSH protocol. A limited
109 subset of signals is supported and only for login or command sessions
110 (i.e. not subsystems) that were not subject to a forced command via
111 authorized_keys or sshd_config.
112 - ssh(1): support "ssh -Q sig" to list supported signature options.
113 Also "ssh -Q help" to show the full set of supported queries.
114 - ssh(1), sshd(8): add a CASignatureAlgorithms option for the client and
115 server configs to allow control over which signature formats are
116 allowed for CAs to sign certificates. For example, this allows
117 banning CAs that sign certificates using the RSA-SHA1 signature
118 algorithm.
119 - sshd(8), ssh-keygen(1): allow key revocation lists (KRLs) to revoke
120 keys specified by SHA256 hash.
121 - ssh-keygen(1): allow creation of key revocation lists directly from
122 base64-encoded SHA256 fingerprints. This supports revoking keys using
123 only the information contained in sshd(8) authentication log messages.
124 - ssh(1), ssh-keygen(1): avoid spurious "invalid format" errors when
125 attempting to load PEM private keys while using an incorrect
126 passphrase.
127 - sshd(8): when a channel closed message is received from a client,
128 close the stderr file descriptor at the same time stdout is closed.
129 This avoids stuck processes if they were waiting for stderr to close
130 and were insensitive to stdin/out closing (closes: #844494).
131 - ssh(1): allow ForwardX11Timeout=0 to disable the untrusted X11
132 forwarding timeout and support X11 forwarding indefinitely.
133 Previously the behaviour of ForwardX11Timeout=0 was undefined.
134 - sshd(8): when compiled with GSSAPI support, cache supported method
135 OIDs regardless of whether GSSAPI authentication is enabled in the
136 main section of sshd_config. This avoids sandbox violations if GSSAPI
137 authentication was later enabled in a Match block.
138 - sshd(8): do not fail closed when configured with a text key revocation
139 list that contains a too-short key.
140 - ssh(1): treat connections with ProxyJump specified the same as ones
141 with a ProxyCommand set with regards to hostname canonicalisation
142 (i.e. don't try to canonicalise the hostname unless
143 CanonicalizeHostname is set to 'always').
144 - ssh(1): fix regression in OpenSSH 7.8 that could prevent public-key
145 authentication using certificates hosted in a ssh-agent(1) or against
146 sshd(8) from OpenSSH <7.8 (LP: #1790963).
147 - All: support building against the openssl-1.1 API (releases 1.1.0g and
148 later). The openssl-1.0 API will remain supported at least until
149 OpenSSL terminates security patch support for that API version
150 (closes: #828475).
151 - sshd(8): allow the futex(2) syscall in the Linux seccomp sandbox;

157 than it solves (thanks, Christian Ehrhardt, Andreas Hasenack, and David
158 Britton; closes: #789532, LP: #1037738, #1674330, #1718227). Add an

165
166 * New upstream release (https://www.openssh.com/txt/release-7.8, closes:
167 #907534):
168 - ssh-keygen(1): Write OpenSSH format private keys by default instead of
169 using OpenSSL's PEM format (closes: #905407). The OpenSSH format,
170 supported in OpenSSH releases since 2014 and described in the
171 PROTOCOL.key file in the source distribution, offers substantially
172 better protection against offline password guessing and supports key
173 comments in private keys. If necessary, it is possible to write old
174 PEM-style keys by adding "-m PEM" to ssh-keygen's arguments when
175 generating or updating a key.
176 - sshd(8): Remove internal support for S/Key multiple factor
177 authentication. S/Key may still be used via PAM or BSD auth.
178 - ssh(1): Remove vestigial support for running ssh(1) as setuid. This
179 used to be required for hostbased authentication and the (long gone)
180 rhosts-style authentication, but has not been necessary for a long
181 time. Attempting to execute ssh as a setuid binary, or with uid !=
182 effective uid will now yield a fatal error at runtime.
183 - sshd(8): The semantics of PubkeyAcceptedKeyTypes and the similar
184 HostbasedAcceptedKeyTypes options have changed. These now specify
185 signature algorithms that are accepted for their respective
186 authentication mechanism, where previously they specified accepted key
187 types. This distinction matters when using the RSA/SHA2 signature
188 algorithms "rsa-sha2-256", "rsa-sha2-512" and their certificate
189 counterparts. Configurations that override these options but omit
190 these algorithm names may cause unexpected authentication failures (no
191 action is required for configurations that accept the default for
192 these options).
193 - sshd(8): The precedence of session environment variables has changed.
194 ~/.ssh/environment and environment="..." options in authorized_keys
195 files can no longer override SSH_* variables set implicitly by sshd.
196 - ssh(1)/sshd(8): The default IPQoS used by ssh/sshd has changed. They
197 will now use DSCP AF21 for interactive traffic and CS1 for bulk. For
198 a detailed rationale, please see the commit message:
199 https://cvsweb.openbsd.org/src/usr.bin/ssh/readconf.c#rev1.284
200 - ssh(1)/sshd(8): Add new signature algorithms "rsa-sha2-256-cert-
201 v01@openssh.com" and "rsa-sha2-512-cert-v01@openssh.com" to explicitly
202 force use of RSA/SHA2 signatures in authentication.
203 - sshd(8): Extend the PermitUserEnvironment option to accept a whitelist
204 of environment variable names in addition to global "yes" or "no"
205 settings.
206 - sshd(8): Add a PermitListen directive to sshd_config(5) and a
207 corresponding permitlisten= authorized_keys option that control which
208 listen addresses and port numbers may be used by remote forwarding
209 (ssh -R ...).
210 - sshd(8): Add some countermeasures against timing attacks used for
211 account validation/enumeration. sshd will enforce a minimum time or
212 each failed authentication attempt consisting of a global 5ms minimum
213 plus an additional per-user 0-4ms delay derived from a host secret.
214 - sshd(8): Add a SetEnv directive to allow an administrator to
215 explicitly specify environment variables in sshd_config. Variables
216 set by SetEnv override the default and client-specified environment.
217 - ssh(1): Add a SetEnv directive to request that the server sets an
218 environment variable in the session. Similar to the existing SendEnv
219 option, these variables are set subject to server configuration.
220 - ssh(1): Allow "SendEnv -PATTERN" to clear environment variables
221 previously marked for sending to the server (closes: #573316).
222 - ssh(1)/sshd(8): Make UID available as a %-expansion everywhere that
223 the username is available currently.
224 - ssh(1): Allow setting ProxyJump=none to disable ProxyJump
225 functionality.
226 - sshd(8): Avoid observable differences in request parsing that could be
227 used to determine whether a target user is valid.
228 - ssh(1)/sshd(8): Fix some memory leaks.
229 - ssh(1): Fix a pwent clobber (introduced in openssh-7.7) that could
230 occur during key loading, manifesting as crash on some platforms.
231 - sshd_config(5): Clarify documentation for AuthenticationMethods
232 option.
233 - ssh(1): Ensure that the public key algorithm sent in a public key
234 SSH_MSG_USERAUTH_REQUEST matches the content of the signature blob.
235 Previously, these could be inconsistent when a legacy or non-OpenSSH
236 ssh-agent returned a RSA/SHA1 signature when asked to make a RSA/SHA2
237 signature.
238 - sshd(8): Fix failures to read authorized_keys caused by faulty
239 supplemental group caching.
240 - scp(1): Apply umask to directories, fixing potential mkdir/chmod race
241 when copying directory trees.
242 - ssh-keygen(1): Return correct exit code when searching for and hashing
243 known_hosts entries in a single operation.
244 - ssh(1): Prefer the ssh binary pointed to via argv[0] to $PATH when
245 re-executing ssh for ProxyJump.
246 - sshd(8): Do not ban PTY allocation when a sshd session is restricted
247 because the user password is expired as it breaks password change
248 dialog.
249 - ssh(1)/sshd(8): Fix error reporting from select() failures.
250 - ssh(1): Improve documentation for -w (tunnel) flag, emphasising that
251 -w implicitly sets Tunnel=point-to-point.
252 - ssh-agent(1): Implement EMFILE mitigation for ssh-agent. ssh-agent
253 will no longer spin when its file descriptor limit is exceeded.
254 - ssh(1)/sshd(8): Disable SSH2_MSG_DEBUG messages for Twisted Conch
255 clients. Twisted Conch versions that lack a version number in their
256 identification strings will mishandle these messages when running on
257 Python 2.x (https://twistedmatrix.com/trac/ticket/9422).
258 - sftp(1): Notify user immediately when underlying ssh process dies
259 expectedly.
260 - ssh(1)/sshd(8): Fix tunnel forwarding; regression in 7.7 release.
261 - ssh-agent(1): Don't kill ssh-agent's listening socket entirely if it
262 fails to accept(2) a connection.
263 - ssh(1): Add some missing options in the configuration dump output (ssh
264 -G).
265 - sshd(8): Expose details of completed authentication to PAM auth
266 modules via SSH_AUTH_INFO_0 in the PAM environment.
267 * Switch debian/watch to HTTPS.
268 * Temporarily work around https://twistedmatrix.com/trac/ticket/9515 in
269 regression tests.

303
304openssh (1:7.7p1-1) unstable; urgency=medium
305
306 * New upstream release (https://www.openssh.com/txt/release-7.7):
307 - ssh(1)/sshd(8): Drop compatibility support for some very old SSH
308 implementations, including ssh.com <=2.* and OpenSSH <= 3.*. These
309 versions were all released in or before 2001 and predate the final SSH
310 RFCs. The support in question isn't necessary for RFC-compliant SSH
311 implementations.
312 - Add experimental support for PQC XMSS keys (Extended Hash-Based
313 Signatures).
314 - sshd(8): Add an "rdomain" criterion for the sshd_config Match keyword
315 to allow conditional configuration that depends on which routing
316 domain a connection was received on.
317 - sshd_config(5): Add an optional rdomain qualifier to the ListenAddress
318 directive to allow listening on different routing domains.
319 - sshd(8): Add "expiry-time" option for authorized_keys files to allow
320 for expiring keys.
321 - ssh(1): Add a BindInterface option to allow binding the outgoing
322 connection to an interface's address (basically a more usable
323 BindAddress; closes: #289592).
324 - ssh(1): Expose device allocated for tun/tap forwarding via a new %T
325 expansion for LocalCommand. This allows LocalCommand to be used to
326 prepare the interface.
327 - sshd(8): Expose the device allocated for tun/tap forwarding via a new
328 SSH_TUNNEL environment variable. This allows automatic setup of the
329 interface and surrounding network configuration automatically on the
330 server.
331 - ssh(1)/scp(1)/sftp(1): Add URI support to ssh, sftp and scp, e.g.
332 ssh://user@host or sftp://user@host/path. Additional connection
333 parameters described in draft-ietf-secsh-scp-sftp-ssh-uri-04 are not
334 implemented since the ssh fingerprint format in the draft uses the
335 deprecated MD5 hash with no way to specify any other algorithm.
336 - ssh-keygen(1): Allow certificate validity intervals that specify only
337 a start or stop time (instead of both or neither).
338 - sftp(1): Allow "cd" and "lcd" commands with no explicit path argument.
339 lcd will change to the local user's home directory as usual. cd will
340 change to the starting directory for session (because the protocol
341 offers no way to obtain the remote user's home directory).
342 - sshd(8): When doing a config test with sshd -T, only require the
343 attributes that are actually used in Match criteria rather than (an
344 incomplete list of) all criteria.
345 - ssh(1)/sshd(8): More strictly check signature types during key
346 exchange against what was negotiated. Prevents downgrade of RSA
347 signatures made with SHA-256/512 to SHA-1.
348 - sshd(8): Fix support for client that advertise a protocol version of
349 "1.99" (indicating that they are prepared to accept both SSHv1 and
350 SSHv2). This was broken in OpenSSH 7.6 during the removal of SSHv1
351 support.
352 - ssh(1): Warn when the agent returns a ssh-rsa (SHA1) signature when a
353 rsa-sha2-256/512 signature was requested. This condition is possible
354 when an old or non-OpenSSH agent is in use.
355 - ssh-agent(1): Fix regression introduced in 7.6 that caused ssh-agent
356 to fatally exit if presented an invalid signature request message.
357 - sshd_config(5): Accept yes/no flag options case-insensitively, as has
358 been the case in ssh_config(5) for a long time (LP: #1656557).
359 - ssh(1): Improve error reporting for failures during connection. Under
360 some circumstances misleading errors were being shown.
361 - ssh-keyscan(1): Add -D option to allow printing of results directly in
362 SSHFP format.
363 - ssh(1): Compatibility fix for some servers that erroneously drop the
364 connection when the IUTF8 (RFC8160) option is sent.
365 - scp(1): Disable RemoteCommand and RequestTTY in the ssh session
366 started by scp (sftp was already doing this).
367 - ssh-keygen(1): Refuse to create a certificate with an unusable number
368 of principals.
369 - ssh-keygen(1): Fatally exit if ssh-keygen is unable to write all the
370 public key during key generation. Previously it would silently ignore
371 errors writing the comment and terminating newline.
372 - ssh(1): Do not modify hostname arguments that are addresses by
373 automatically forcing them to lower-case. Instead canonicalise them
374 jo resolve ambiguities (e.g. ::0001 => ::1) before they are matched
375 against known_hosts.
376 - ssh(1): Don't accept junk after "yes" or "no" responses to hostkey
377 prompts.
378 - sftp(1): Have sftp print a warning about shell cleanliness when
379 decoding the first packet fails, which is usually caused by shells
380 polluting stdout of non-interactive startups.
381 - ssh(1)/sshd(8): Switch timers in packet code from using wall-clock
382 time to monotonic time, allowing the packet layer to better function
383 over a clock step and avoiding possible integer overflows during
384 steps.
385 - sshd(8): Correctly detect MIPS ABI in use at configure time. Fixes
386 sandbox violations on some environments.
387 - Build and link with "retpoline" flags when available to mitigate the
388 "branch target injection" style (variant 2) of the Spectre
389 branch-prediction vulnerability.

438 * New upstream release (https://www.openssh.com/txt/release-7.6):
439 - CVE-2017-15906: sftp-server(8): In read-only mode, sftp-server was
440 incorrectly permitting creation of zero-length files. Reported by
441 Michal Zalewski.
442 - ssh(1): Delete SSH protocol version 1 support, associated
443 configuration options and documentation (LP: #1584321).
444 - ssh(1)/sshd(8): Remove support for the hmac-ripemd160 MAC.
445 - ssh(1)/sshd(8): Remove support for the arcfour, blowfish and CAST
446 ciphers.
447 - Refuse RSA keys <1024 bits in length and improve reporting for keys
448 that do not meet this requirement.
449 - ssh(1): Do not offer CBC ciphers by default.
450 - ssh(1): Add RemoteCommand option to specify a command in the ssh
451 config file instead of giving it on the client's command line. This
452 allows the configuration file to specify the command that will be
453 executed on the remote host.
454 - sshd(8): Add ExposeAuthInfo option that enables writing details of the
455 authentication methods used (including public keys where applicable)
456 to a file that is exposed via a $SSH_USER_AUTH environment variable in
457 the subsequent session.
458 - ssh(1): Add support for reverse dynamic forwarding. In this mode, ssh
459 will act as a SOCKS4/5 proxy and forward connections to destinations
460 requested by the remote SOCKS client. This mode is requested using
461 extended syntax for the -R and RemoteForward options and, because it
462 is implemented solely at the client, does not require the server be
463 updated to be supported.
464 - sshd(8): Allow LogLevel directive in sshd_config Match blocks.
465 - ssh-keygen(1): Allow inclusion of arbitrary string or flag certificate
466 extensions and critical options.
467 - ssh-keygen(1): Allow ssh-keygen to use a key held in ssh-agent as a CA
468 when signing certificates.
469 - ssh(1)/sshd(8): Allow IPQoS=none in ssh/sshd to not set an explicit
470 ToS/DSCP value and just use the operating system default.
471 - ssh-add(1): Add -q option to make ssh-add quiet on success.
472 - ssh(1): Expand the StrictHostKeyChecking option with two new settings.
473 The first "accept-new" will automatically accept hitherto-unseen keys
474 but will refuse connections for changed or invalid hostkeys. This is
475 a safer subset of the current behaviour of StrictHostKeyChecking=no.
476 The second setting "off", is a synonym for the current behaviour of
477 StrictHostKeyChecking=no: accept new host keys, and continue
478 connection for hosts with incorrect hostkeys. A future release will
479 change the meaning of StrictHostKeyChecking=no to the behaviour of
480 "accept-new".
481 - ssh(1): Add SyslogFacility option to ssh(1) matching the equivalent
482 option in sshd(8).
483 - ssh(1): Use HostKeyAlias if specified instead of hostname for matching
484 host certificate principal names.
485 - sftp(1): Implement sorting for globbed ls.
486 - ssh(1): Add a user@host prefix to client's "Permission denied"
487 messages, useful in particular when using "stacked" connections (e.g.
488 ssh -J) where it's not clear which host is denying.
489 - ssh(1): Accept unknown EXT_INFO extension values that contain \0
490 characters. These are legal, but would previously cause fatal
491 connection errors if received.
492 - sftp(1): Print '?' instead of incorrect link count (that the protocol
493 doesn't provide) for remote listings.
494 - ssh(1): Return failure rather than fatal() for more cases during
495 session multiplexing negotiations. Causes the session to fall back to
496 a non-mux connection if they occur.
497 - ssh(1): Mention that the server may send debug messages to explain
498 public key authentication problems under some circumstances.
499 - Translate OpenSSL error codes to better report incorrect passphrase
500 errors when loading private keys.
501 - sshd(8): Adjust compatibility patterns for WinSCP to correctly
502 identify versions that implement only the legacy DH group exchange
503 scheme (closes: #877800).
504 - ssh(1): Print the "Killed by signal 1" message only at LogLevel
505 verbose so that it is not shown at the default level; prevents it from
506 appearing during ssh -J and equivalent ProxyCommand configs.
507 - ssh-keygen(1): When generating all hostkeys (ssh-keygen -A), clobber
508 existing keys if they exist but are zero length. Zero-length keys
509 could previously be made if ssh-keygen failed or was interrupted part
510 way through generating them.
511 - ssh-keyscan(1): Avoid double-close() on file descriptors.
512 - sshd(8): Avoid reliance on shared use of pointers shared between
513 monitor and child sshd processes.
514 - sshd_config(8): Document available AuthenticationMethods.
515 - ssh(1): Avoid truncation in some login prompts.
516 - ssh(1): Make "--" before the hostname terminate argument processing
517 after the hostname too (closes: #873201).
518 - ssh-keygen(1): Switch from aes256-cbc to aes256-ctr for encrypting
519 new-style private keys.
520 - ssh(1): Warn and do not attempt to use keys when the public and
521 private halves do not match.
522 - sftp(1): Don't print verbose error message when ssh disconnects from
523 under sftp.
524 - sshd(8): Fix keepalive scheduling problem: prevent activity on a
525 forwarded port from preventing the keepalive from being sent.
526 - sshd(8): When started without root privileges, don't require the
527 privilege separation user or path to exist.
528 - ssh(1)/sshd(8): Correctness fix for channels implementation: accept
529 channel IDs greater than 0x7FFFFFFF.
530 - sshd(8): Expose list of completed authentication methods to PAM via
531 the SSH_AUTH_INFO_0 PAM environment variable.
532 - ssh(1)/sshd(8): Fix several problems in the tun/tap forwarding code,
533 mostly to do with host/network byte order confusion.
534 - sshd(8): Avoid Linux seccomp violations on ppc64le over the socketcall
535 syscall.
536 * Build-depend on debhelper (>= 9.20160709~) rather than dh-systemd.

641
642 * New upstream release (https://www.openssh.com/txt/release-7.5):
643 - SECURITY: ssh(1), sshd(8): Fix weakness in CBC padding oracle
644 countermeasures that allowed a variant of the attack fixed in OpenSSH
645 7.3 to proceed. Note that the OpenSSH client disables CBC ciphers by
646 default, sshd offers them as lowest-preference options and will remove
647 them by default entirely in the next release.
648 - This release deprecates the sshd_config UsePrivilegeSeparation option,
649 thereby making privilege separation mandatory (closes: #407754).
650 - The format of several log messages emitted by the packet code has
651 changed to include additional information about the user and their
652 authentication state. Software that monitors ssh/sshd logs may need
653 to account for these changes.
654 - ssh(1), sshd(8): Support "=-" syntax to easily remove methods from
655 algorithm lists, e.g. Ciphers=-*cbc.
656 - sshd(1): Fix NULL dereference crash when key exchange start messages
657 are sent out of sequence.
658 - ssh(1), sshd(8): Allow form-feed characters to appear in configuration
659 files.
660 - sshd(8): Fix regression in OpenSSH 7.4 support for the server-sig-algs
661 extension, where SHA2 RSA signature methods were not being correctly
662 advertised.
663 - ssh(1), ssh-keygen(1): Fix a number of case-sensitivity bugs in
664 known_hosts processing.
665 - ssh(1): Allow ssh to use certificates accompanied by a private key
666 file but no corresponding plain *.pub public key.
667 - ssh(1): When updating hostkeys using the UpdateHostKeys option, accept
668 RSA keys if HostkeyAlgorithms contains any RSA keytype. Previously,
669 ssh could ignore RSA keys when only the ssh-rsa-sha2-* methods were
670 enabled in HostkeyAlgorithms and not the old ssh-rsa method.
671 - ssh(1): Detect and report excessively long configuration file lines.
672 - Merge a number of fixes found by Coverity and reported via Redhat and
673 FreeBSD. Includes fixes for some memory and file descriptor leaks in
674 error paths.
675 - ssh(1), sshd(8): When logging long messages to stderr, don't truncate
676 "\r\n" if the length of the message exceeds the buffer.
677 - ssh(1): Fully quote [host]:port in generated ProxyJump/-J command-
678 line; avoid confusion over IPv6 addresses and shells that treat square
679 bracket characters specially.
680 - Fix various fallout and sharp edges caused by removing SSH protocol 1
681 support from the server, including the server banner string being
682 incorrectly terminated with only \n (instead of \r\n), confusing error
683 messages from ssh-keyscan, and a segfault in sshd if protocol v.1 was
684 enabled for the client and sshd_config contained references to legacy
685 keys.
686 - ssh(1), sshd(8): Free fd_set on connection timeout.
687 - sftp(1): Fix division by zero crash in "df" output when server returns
688 zero total filesystem blocks/inodes.
689 - ssh(1), ssh-add(1), ssh-keygen(1), sshd(8): Translate OpenSSL errors
690 encountered during key loading to more meaningful error codes.
691 - ssh-keygen(1): Sanitise escape sequences in key comments sent to
692 printf but preserve valid UTF-8 when the locale supports it.
693 - ssh(1), sshd(8): Return reason for port forwarding failures where
694 feasible rather than always "administratively prohibited".
695 - sshd(8): Fix deadlock when AuthorizedKeysCommand or
696 AuthorizedPrincipalsCommand produces a lot of output and a key is
697 matched early.
698 - ssh(1): Fix typo in ~C error message for bad port forward
699 cancellation.
700 - ssh(1): Show a useful error message when included config files can't
701 be opened.
702 - sshd_config(5): Repair accidentally-deleted mention of %k token in
703 AuthorizedKeysCommand.
704 - sshd(8): Remove vestiges of previously removed LOGIN_PROGRAM.
705 - ssh-agent(1): Relax PKCS#11 whitelist to include libexec and common
706 32-bit compatibility library directories.
707 - sftp-client(1): Fix non-exploitable integer overflow in SSH2_FXP_NAME
708 response handling.
709 - ssh-agent(1): Fix regression in 7.4 of deleting PKCS#11-hosted keys.
710 It was not possible to delete them except by specifying their full
711 physical path.
712 - sshd(8): Avoid sandbox errors for Linux S390 systems using an ICA
713 crypto coprocessor.
714 - sshd(8): Fix non-exploitable weakness in seccomp-bpf sandbox arg
715 inspection.
716 - ssh-keygen(1), ssh(1), sftp(1): Fix output truncation for various that
717 contain non-printable characters where the codeset in use is ASCII.

816openssh (1:7.4p1-1) unstable; urgency=medium
817
818 * New upstream release (http://www.openssh.com/txt/release-7.4):
819 - ssh(1): Remove 3des-cbc from the client's default proposal. 64-bit
820 block ciphers are not safe in 2016 and we don't want to wait until
821 attacks like SWEET32 are extended to SSH. As 3des-cbc was the only
822 mandatory cipher in the SSH RFCs, this may cause problems connecting
823 to older devices using the default configuration, but it's highly
824 likely that such devices already need explicit configuration for key
825 exchange and hostkey algorithms already anyway.
826 - sshd(8): When a forced-command appears in both a certificate and an
827 authorized keys/principals command= restriction, sshd will now refuse
828 to accept the certificate unless they are identical. The previous
829 (documented) behaviour of having the certificate forced-command
830 override the other could be a bit confusing and error-prone.
831 - sshd(8): Remove the UseLogin configuration directive and support for
832 having /bin/login manage login sessions.
833 - CVE-2016-10009: ssh-agent(1): Will now refuse to load PKCS#11 modules
834 from paths outside a trusted whitelist (run-time configurable).
835 Requests to load modules could be passed via agent forwarding and an
836 attacker could attempt to load a hostile PKCS#11 module across the
837 forwarded agent channel: PKCS#11 modules are shared libraries, so this
838 would result in code execution on the system running the ssh-agent if
839 the attacker has control of the forwarded agent-socket (on the host
840 running the sshd server) and the ability to write to the filesystem of
841 the host running ssh-agent (usually the host running the ssh client)
842 (closes: #848714).
843 - CVE-2016-10010: sshd(8): When privilege separation is disabled,
844 forwarded Unix-domain sockets would be created by sshd(8) with the
845 privileges of 'root' instead of the authenticated user. This release
846 refuses Unix-domain socket forwarding when privilege separation is
847 disabled (Privilege separation has been enabled by default for 14
848 years) (closes: #848715).
849 - CVE-2016-10011: sshd(8): Avoid theoretical leak of host private key
850 material to privilege-separated child processes via realloc() when
851 reading keys. No such leak was observed in practice for normal-sized
852 keys, nor does a leak to the child processes directly expose key
853 material to unprivileged users (closes: #848716).
854 - CVE-2016-10012: sshd(8): The shared memory manager used by
855 pre-authentication compression support had a bounds checks that could
856 be elided by some optimising compilers. Additionally, this memory
857 manager was incorrectly accessible when pre-authentication compression
858 was disabled. This could potentially allow attacks against the
859 privileged monitor process from the sandboxed privilege-separation
860 process (a compromise of the latter would be required first). This
861 release removes support for pre-authentication compression from
862 sshd(8) (closes: #848717).
863 - SECURITY: sshd(8): Validate address ranges for AllowUser and DenyUsers
864 directives at configuration load time and refuse to accept invalid
865 ones. It was previously possible to specify invalid CIDR address
866 ranges (e.g. user@127.1.2.3/55) and these would always match, possibly
867 resulting in granting access where it was not intended.
868 - ssh(1): Add a proxy multiplexing mode to ssh(1) inspired by the
869 version in PuTTY by Simon Tatham. This allows a multiplexing client
870 to communicate with the master process using a subset of the SSH
871 packet and channels protocol over a Unix-domain socket, with the main
872 process acting as a proxy that translates channel IDs, etc. This
873 allows multiplexing mode to run on systems that lack file-descriptor
874 passing (used by current multiplexing code) and potentially, in
875 conjunction with Unix-domain socket forwarding, with the client and
876 multiplexing master process on different machines. Multiplexing proxy
877 mode may be invoked using "ssh -O proxy ...".
878 - sshd(8): Add a sshd_config DisableForwarding option that disables X11,
879 agent, TCP, tunnel and Unix domain socket forwarding, as well as
880 anything else we might implement in the future. Like the 'restrict'
881 authorized_keys flag, this is intended to be a simple and future-proof
882 way of restricting an account.
883 - sshd(8), ssh(1): Support the "curve25519-sha256" key exchange method.
884 This is identical to the currently-supported method named
885 "curve25519-sha256@libssh.org".
886 - sshd(8): Improve handling of SIGHUP by checking to see if sshd is
887 already daemonised at startup and skipping the call to daemon(3) if it
888 is. This ensures that a SIGHUP restart of sshd(8) will retain the
889 same process-ID as the initial execution. sshd(8) will also now
890 unlink the PidFile prior to SIGHUP restart and re-create it after a
891 successful restart, rather than leaving a stale file in the case of a
892 configuration error.
893 - sshd(8): Allow ClientAliveInterval and ClientAliveCountMax directives
894 to appear in sshd_config Match blocks.
895 - sshd(8): Add %-escapes to AuthorizedPrincipalsCommand to match those
896 supported by AuthorizedKeysCommand (key, key type, fingerprint, etc.)
897 and a few more to provide access to the contents of the certificate
898 being offered.
899 - ssh(1): Allow IdentityFile to successfully load and use certificates
900 that have no corresponding bare public key.
901 - ssh(1): Fix public key authentication when multiple authentication is
902 in use and publickey is not just the first method attempted.
903 - ssh(1): Improve reporting when attempting to load keys from PKCS#11
904 tokens with fewer useless log messages and more detail in debug
905 messages.
906 - ssh(1): When tearing down ControlMaster connections, don't pollute
907 stderr when LogLevel=quiet.
908 - sftp(1): On ^Z wait for underlying ssh(1) to suspend before suspending
909 sftp(1) to ensure that ssh(1) restores the terminal mode correctly if
910 suspended during a password prompt.
911 - ssh(1): Avoid busy-wait when ssh(1) is suspended during a password
912 prompt (LP: #1646813).
913 - ssh(1), sshd(8): Correctly report errors during sending of ext-info
914 messages.
915 - sshd(8): Fix NULL-deref crash if sshd(8) received an out-of-sequence
916 NEWKEYS message.
917 - sshd(8): Correct list of supported signature algorithms sent in the
918 server-sig-algs extension.
919 - sshd(8): Fix sending ext_info message if privsep is disabled.
920 - sshd(8): More strictly enforce the expected ordering of privilege
921 separation monitor calls used for authentication and allow them only
922 when their respective authentication methods are enabled in the
923 configuration.
924 - sshd_config(5): Use 2001:db8::/32, the official IPv6 subnet for
925 configuration examples.
926 - On environments configured with Turkish locales, fall back to the
927 C/POSIX locale to avoid errors in configuration parsing caused by that
928 locale's unique handling of the letters 'i' and 'I' (LP: #1638338).
929 - contrib: Add a gnome-ssh-askpass3 with GTK+3 support.
930 - sshd(8): Improve PRNG reseeding across privilege separation and force
931 libcrypto to obtain a high-quality seed before chroot or sandboxing.
932 * Apply "wrap-and-sort -at -f debian/control -f debian/tests/control".
933 * Remove entries related to protocol 1 from the default sshd_config
934 generated on new installations.
935 * Remove some advice related to protocol 1 from README.Debian.
936 * Start handling /etc/ssh/sshd_config using ucf. The immediate motivation
937 for this is to deal with deprecations of options related to protocol 1,
938 but something like this has been needed for a long time (closes:
939 #419574, #848089):
940 - sshd_config is now a slightly-patched version of upstream's, and only
941 contains non-default settings (closes: #147201).
942 - I've included as many historical md5sums of default versions of
943 sshd_config as I could reconstruct from version control, but I'm sure
944 I've missed some.
945 - Explicitly synchronise the debconf database with the current
946 configuration file state in openssh-server.config, to ensure that the
947 PermitRootLogin setting is properly preserved.
948 - UsePrivilegeSeparation now defaults to the stronger "sandbox" rather
949 than "yes", per upstream.
950 * Remove redundant "GSSAPIDelegateCredentials no" from ssh_config (already
951 the upstream default), and document that setting ServerAliveInterval to
952 300 by default if BatchMode is set is Debian-specific (closes: #765630).
953 * Build gnome-ssh-askpass with GTK+ 3 (LP: #801187).
954 * When running regression tests under autopkgtest, use a non-root user
955 with passwordless sudo.

1005 padding oracle countermeasures. Note that CBC ciphers are disabled by
1006 default and only included for legacy compatibility.
1007 - SECURITY: ssh(1), sshd(8): Improve operation ordering of MAC
1008 verification for Encrypt-then-MAC (EtM) mode transport MAC algorithms
1009 to verify the MAC before decrypting any ciphertext. This removes the
1010 possibility of timing differences leaking facts about the plaintext,
1011 though no such leakage has been observed.
1012 - ssh(1): Add a ProxyJump option and corresponding -J command-line flag
1013 to allow simplified indirection through a one or more SSH bastions or
1014 "jump hosts".
1015 - ssh(1): Add an IdentityAgent option to allow specifying specific agent
1016 sockets instead of accepting one from the environment.
1017 - ssh(1): Allow ExitOnForwardFailure and ClearAllForwardings to be
1018 optionally overridden when using ssh -W.
1019 - ssh(1), sshd(8): Implement support for the IUTF8 terminal mode as per
1020 draft-sgtatham-secsh-iutf8-00 (closes: #337041, LP: #394570).
1021 - ssh(1), sshd(8): Add support for additional fixed Diffie-Hellman 2K,
1022 4K and 8K groups from draft-ietf-curdle-ssh-kex-sha2-03.
1023 - ssh-keygen(1), ssh(1), sshd(8): Support SHA256 and SHA512 RSA
1024 signatures in certificates.
1025 - ssh(1): Add an Include directive for ssh_config(5) files (closes:
1026 #536031).
1027 - ssh(1): Permit UTF-8 characters in pre-authentication banners sent
1028 from the server.
1029 - ssh(1), sshd(8): Reduce the syslog level of some relatively common
1030 protocol events from LOG_CRIT.
1031 - sshd(8): Refuse AuthenticationMethods="" in configurations and accept
1032 AuthenticationMethods=any for the default behaviour of not requiring
1033 multiple authentication.
1034 - sshd(8): Remove obsolete and misleading "POSSIBLE BREAK-IN ATTEMPT!"
1035 message when forward and reverse DNS don't match.
1036 - ssh(1): Deduplicate LocalForward and RemoteForward entries to fix
1037 failures when both ExitOnForwardFailure and hostname canonicalisation
1038 are enabled.
1039 - sshd(8): Remove fallback from moduli to obsolete "primes" file that
1040 was deprecated in 2001 (LP: #1528251).
1041 - sshd_config(5): Correct description of UseDNS: it affects ssh hostname
1042 processing for authorized_keys, not known_hosts.
1043 - sshd(8): Send ClientAliveInterval pings when a time-based RekeyLimit
1044 is set; previously keepalive packets were not being sent.
1045 - sshd(8): Whitelist more architectures to enable the seccomp-bpf

1152
1153 * New upstream release (http://www.openssh.com/txt/release-7.2):
1154 - This release disables a number of legacy cryptographic algorithms by
1155 default in ssh:
1156 + Several ciphers blowfish-cbc, cast128-cbc, all arcfour variants and
1157 the rijndael-cbc aliases for AES.
1158 + MD5-based and truncated HMAC algorithms.
1159 These algorithms are already disabled by default in sshd.
1160 - ssh(1), sshd(8): Remove unfinished and unused roaming code (was
1161 already forcibly disabled in OpenSSH 7.1p2).
1162 - ssh(1): Eliminate fallback from untrusted X11 forwarding to trusted
1163 forwarding when the X server disables the SECURITY extension.
1164 - ssh(1), sshd(8): Increase the minimum modulus size supported for
1165 diffie-hellman-group-exchange to 2048 bits.
1166 - sshd(8): Pre-auth sandboxing is now enabled by default (previous
1167 releases enabled it for new installations via sshd_config).
1168 - all: Add support for RSA signatures using SHA-256/512 hash algorithms
1169 based on draft-rsa-dsa-sha2-256-03.txt and draft-ssh-ext-info-04.txt.
1170 - ssh(1): Add an AddKeysToAgent client option which can be set to 'yes',
1171 'no', 'ask', or 'confirm', and defaults to 'no'. When enabled, a
1172 private key that is used during authentication will be added to
1173 ssh-agent if it is running (with confirmation enabled if set to
1174 'confirm').
1175 - sshd(8): Add a new authorized_keys option "restrict" that includes all
1176 current and future key restrictions (no-*-forwarding, etc.). Also add
1177 permissive versions of the existing restrictions, e.g. "no-pty" ->
1178 "pty". This simplifies the task of setting up restricted keys and
1179 ensures they are maximally-restricted, regardless of any permissions
1180 we might implement in the future.
1181 - ssh(1): Add ssh_config CertificateFile option to explicitly list
1182 certificates.
1183 - ssh-keygen(1): Allow ssh-keygen to change the key comment for all
1184 supported formats (closes: #811125).
1185 - ssh-keygen(1): Allow fingerprinting from standard input, e.g.
1186 "ssh-keygen -lf -" (closes: #509058).
1187 - ssh-keygen(1): Allow fingerprinting multiple public keys in a file,
1188 e.g. "ssh-keygen -lf ~/.ssh/authorized_keys".
1189 - sshd(8): Support "none" as an argument for sshd_config Foreground and
1190 ChrootDirectory. Useful inside Match blocks to override a global
1191 default.
1192 - ssh-keygen(1): Support multiple certificates (one per line) and
1193 reading from standard input (using "-f -") for "ssh-keygen -L"
1194 - ssh-keyscan(1): Add "ssh-keyscan -c ..." flag to allow fetching
1195 certificates instead of plain keys.
1196 - ssh(1): Better handle anchored FQDNs (e.g. 'cvs.openbsd.org.') in
1197 hostname canonicalisation - treat them as already canonical and remove
1198 the trailing '.' before matching ssh_config.
1199 - sftp(1): Existing destination directories should not terminate
1200 recursive uploads (regression in OpenSSH 6.8; LP: #1553378).
1201 * Use HTTPS for Vcs-* URLs, and link to cgit rather than gitweb.
1202 * Restore slogin symlinks for compatibility, although they were removed
1203 upstream.

1290 disabled by default at run-time. It may be re-enabled using the
1291 instructions at http://www.openssh.com/legacy.html
1292 - Support for ssh-dss, ssh-dss-cert-* host and user keys is disabled by
1293 default at run-time. These may be re-enabled using the instructions
1294 at http://www.openssh.com/legacy.html
1295 - Support for the legacy v00 cert format has been removed.
1296 - The default for the sshd_config(5) PermitRootLogin option has changed
1297 from "yes" to "prohibit-password".
1298 - PermitRootLogin=without-password/prohibit-password now bans all
1299 interactive authentication methods, allowing only public-key,
1300 hostbased and GSSAPI authentication (previously it permitted
1301 keyboard-interactive and password-less authentication if those were
1302 enabled).
1303 - ssh_config(5): Add PubkeyAcceptedKeyTypes option to control which
1304 public key types are available for user authentication.
1305 - sshd_config(5): Add HostKeyAlgorithms option to control which public
1306 key types are offered for host authentications.
1307 - ssh(1), sshd(8): Extend Ciphers, MACs, KexAlgorithms,
1308 HostKeyAlgorithms, PubkeyAcceptedKeyTypes and HostbasedKeyTypes
1309 options to allow appending to the default set of algorithms instead of
1310 replacing it. Options may now be prefixed with a '+' to append to the
1311 default, e.g. "HostKeyAlgorithms=+ssh-dss".
1312 - sshd_config(5): PermitRootLogin now accepts an argument of
1313 'prohibit-password' as a less-ambiguous synonym of 'without-
1314 password'.
1315 - ssh(1), sshd(8): Add compatability workarounds for Cisco and more
1316 PuTTY versions.
1317 - Fix some omissions and errors in the PROTOCOL and PROTOCOL.mux
1318 documentation relating to Unix domain socket forwarding.
1319 - ssh(1): Improve the ssh(1) manual page to include a better description
1320 of Unix domain socket forwarding (closes: #779068).

1329 - sshd(8): OpenSSH 7.0 contained a logic error in PermitRootLogin=
1330 prohibit-password/without-password that could, depending on
1331 compile-time configuration, permit password authentication to root
1332 while preventing other forms of authentication. This problem was
1333 reported by Mantas Mikulenas.
1334 - ssh(1), sshd(8): Add compatibility workarounds for FuTTY.

1372 * New upstream release (http://www.openssh.com/txt/release-6.8):
1373 - sshd(8): UseDNS now defaults to 'no'. Configurations that match
1374 against the client host name (via sshd_config or authorized_keys) may
1375 need to re-enable it or convert to matching against addresses.
1376 - Add FingerprintHash option to ssh(1) and sshd(8), and equivalent
1377 command-line flags to the other tools to control algorithm used for
1378 key fingerprints. The default changes from MD5 to SHA256 and format
1379 from hex to base64.
1380 Fingerprints now have the hash algorithm prepended. An example of the
1381 new format: SHA256:mVPwvezndPv/ARoIadVY98vAC0g+P/5633yTC4d/wXE
1382 Please note that visual host keys will also be different.
1383 - ssh(1), sshd(8): Experimental host key rotation support. Add a
1384 protocol extension for a server to inform a client of all its
1385 available host keys after authentication has completed. The client
1386 may record the keys in known_hosts, allowing it to upgrade to better
1387 host key algorithms and a server to gracefully rotate its keys.
1388 The client side of this is controlled by a UpdateHostkeys config
1389 option (default off).
1390 - ssh(1): Add a ssh_config HostbasedKeyType option to control which host
1391 public key types are tried during host-based authentication.
1392 - ssh(1), sshd(8): Fix connection-killing host key mismatch errors when
1393 sshd offers multiple ECDSA keys of different lengths.
1394 - ssh(1): When host name canonicalisation is enabled, try to parse host
1395 names as addresses before looking them up for canonicalisation. Fixes
1396 bz#2074 and avoids needless DNS lookups in some cases.
1397 - ssh(1), ssh-keysign(8): Make ed25519 keys work for host based
1398 authentication.
1399 - sshd(8): SSH protocol v.1 workaround for the Meyer, et al,
1400 Bleichenbacher Side Channel Attack. Fake up a bignum key before RSA
1401 decryption.
1402 - sshd(8): Remember which public keys have been used for authentication
1403 and refuse to accept previously-used keys. This allows
1404 AuthenticationMethods=publickey,publickey to require that users
1405 authenticate using two _different_ public keys.
1406 - sshd(8): add sshd_config HostbasedAcceptedKeyTypes and
1407 PubkeyAcceptedKeyTypes options to allow sshd to control what public
1408 key types will be accepted (closes: #481133). Currently defaults to
1409 all.

1415 number or key ID without scoping to a particular CA.
1416 - ssh(1): Add a "Match canonical" criteria that allows ssh_config Match
1417 blocks to trigger only in the second config pass.
1418 - ssh(1): Add a -G option to ssh that causes it to parse its
1419 configuration and dump the result to stdout, similar to "sshd -T".
1420 - ssh(1): Allow Match criteria to be negated. E.g. "Match !host".
1421 - ssh-keyscan(1): ssh-keyscan has been made much more robust against

1431 multiplexing is in use.
1432 - ssh-keygen(1): Fix broken private key conversion from non-OpenSSH
1433 formats.

1435 * New upstream release (http://www.openssh.com/txt/release-6.9):
1436 - CVE-2015-5352: ssh(1): When forwarding X11 connections with
1437 ForwardX11Trusted=no, connections made after ForwardX11Timeout expired
1438 could be permitted and no longer subject to XSECURITY restrictions
1439 because of an ineffective timeout check in ssh(1) coupled with "fail
1440 open" behaviour in the X11 server when clients attempted connections
1441 with expired credentials (closes: #790798). This problem was reported
1442 by Jann Horn.
1443 - SECURITY: ssh-agent(1): Fix weakness of agent locking (ssh-add -x) to
1444 password guessing by implementing an increasing failure delay, storing
1445 a salted hash of the password rather than the password itself and
1446 using a timing-safe comparison function for verifying unlock attempts.
1447 This problem was reported by Ryan Castellucci.
1448 - sshd(8): Support admin-specified arguments to AuthorizedKeysCommand
1449 (closes: #740494).
1450 - sshd(8): Add AuthorizedPrincipalsCommand that allows retrieving
1451 authorized principals information from a subprocess rather than a
1452 file.
1453 - ssh(1), ssh-add(1): Support PKCS#11 devices with external PIN entry
1454 devices.
1455 - ssh-keygen(1): Support "ssh-keygen -lF hostname" to search known_hosts
1456 and print key hashes rather than full keys.
1457 - ssh-agent(1): Add -D flag to leave ssh-agent in foreground without
1458 enabling debug mode.
1459 - ssh(1), sshd(8): Deprecate legacy SSH2_MSG_KEX_DH_GEX_REQUEST_OLD
1460 message and do not try to use it against some 3rd-party SSH
1461 implementations that use it (older PuTTY, WinSCP).
1462 - ssh(1), sshd(8): Cap DH-GEX group size at 4Kbits for Cisco
1463 implementations as some would fail when attempting to use group sizes
1464 >4K (closes: #740307, LP: #1287222).
1465 - ssh(1): Fix out-of-bound read in EscapeChar configuration option
1466 parsing.
1467 - sshd(8): Fix application of PermitTunnel, LoginGraceTime,
1468 AuthenticationMethods and StreamLocalBindMask options in Match blocks.
1469 - ssh(1), sshd(8): Improve disconnection message on TCP reset.
1470 - ssh(1): Remove failed remote forwards established by multiplexing from
1471 the list of active forwards.
1472 - sshd(8): Make parsing of authorized_keys "environment=" options
1473 independent of PermitUserEnv being enabled.
1474 - sshd(8): Fix post-auth crash with permitopen=none (closes: #778807).
1475 - ssh(1), ssh-add(1), ssh-keygen(1): Allow new-format private keys to be
1476 encrypted with AEAD ciphers.
1477 - ssh(1): Allow ListenAddress, Port and AddressFamily configuration
1478 options to appear in any order.
1479 - sshd(8): Check for and reject missing arguments for VersionAddendum
1480 and ForceCommand.
1481 - ssh(1), sshd(8): Don't treat unknown certificate extensions as fatal.
1482 - ssh-keygen(1): Make stdout and stderr output consistent.
1483 - ssh(1): Mention missing DISPLAY environment in debug log when X11
1484 forwarding requested.
1485 - sshd(8): Correctly record login when UseLogin is set.
1486 - sshd(8): Add some missing options to sshd -T output and fix output of
1487 VersionAddendum and HostCertificate.
1488 - Document and improve consistency of options that accept a "none"
1489 argument: TrustedUserCAKeys, RevokedKeys, AuthorizedPrincipalsFile.
1490 - ssh(1): Include remote username in debug output.
1491 - sshd(8): Avoid compatibility problem with some versions of Tera Term,
1492 which would crash when they received the hostkeys notification message
1493 (hostkeys-00@openssh.com).
1494 - sshd(8): Mention ssh-keygen -E as useful when comparing legacy MD5
1495 host key fingerprints.
1496 - ssh(1): Clarify pseudo-terminal request behaviour and make manual
1497 language consistent.
1498 - ssh(1): Document that the TERM environment variable is not subject to
1499 SendEnv and AcceptEnv; bz#2386
1500 - sshd(8): Format UsePAM setting when using sshd -T (closes: #767648).
1501 - moduli(5): Update DH-GEX moduli (closes: #787037).
1502 * There are some things I want to fix before upgrading to 7.0p1, though I
1503 intend to do that soon. In the meantime, backport some patches, mainly
1504 to fix security issues:
1505 - SECURITY: sshd(8): OpenSSH 6.8 and 6.9 incorrectly set TTYs to be
1506 world-writable. Local attackers may be able to write arbitrary
1507 messages to logged-in users, including terminal escape sequences.
1508 Reported by Nikolay Edigaryev.
1509 - SECURITY: sshd(8): Fixed a privilege separation weakness related to
1510 PAM support. Attackers who could successfully compromise the
1511 pre-authentication process for remote code execution and who had valid
1512 credentials on the host could impersonate other users. Reported by
1513 Moritz Jodeit.
1514 - SECURITY: sshd(8): Fixed a use-after-free bug related to PAM support
1515 that was reachable by attackers who could compromise the
1516 pre-authentication process for remote code execution (closes:
1517 #795711). Also reported by Moritz Jodeit.
1518 - CVE-2015-5600: sshd(8): Fix circumvention of MaxAuthTries using
1519 keyboard-interactive authentication (closes: #793616). By specifying
1520 a long, repeating keyboard-interactive "devices" string, an attacker
1521 could request the same authentication method be tried thousands of
1522 times in a single pass. The LoginGraceTime timeout in sshd(8) and any
1523 authentication failure delays implemented by the authentication
1524 mechanism itself were still applied. Found by Kingcope.
1525 - Let principals-command.sh work for noexec /var/run.
1526 * Thanks to Jakub Jelen of Red Hat for Fedora's rebased version of the
1527 GSSAPI key exchange patch.
1528 * Document the Debian-specific change to the default value of
1529 ForwardX11Trusted in ssh(1) (closes: #781469).

1586
1587 * New upstream release (http://www.openssh.com/txt/release-6.7):
1588 - sshd(8): The default set of ciphers and MACs has been altered to
1589 remove unsafe algorithms. In particular, CBC ciphers and arcfour* are
1590 disabled by default. The full set of algorithms remains available if
1591 configured explicitly via the Ciphers and MACs sshd_config options.
1592 - ssh(1), sshd(8): Add support for Unix domain socket forwarding. A
1593 remote TCP port may be forwarded to a local Unix domain socket and
1594 vice versa or both ends may be a Unix domain socket (closes: #236718).
1595 - ssh(1), ssh-keygen(1): Add support for SSHFP DNS records for ED25519
1596 key types.
1597 - sftp(1): Allow resumption of interrupted uploads.
1598 - ssh(1): When rekeying, skip file/DNS lookups of the hostkey if it is
1599 the same as the one sent during initial key exchange.
1600 - sshd(8): Allow explicit ::1 and 127.0.0.1 forwarding bind addresses
1601 when GatewayPorts=no; allows client to choose address family.
1602 - sshd(8): Add a sshd_config PermitUserRC option to control whether
1603 ~/.ssh/rc is executed, mirroring the no-user-rc authorized_keys
1604 option.
1605 - ssh(1): Add a %C escape sequence for LocalCommand and ControlPath that
1606 expands to a unique identifier based on a hash of the tuple of (local
1607 host, remote user, hostname, port). Helps avoid exceeding miserly
1608 pathname limits for Unix domain sockets in multiplexing control paths.
1609 - sshd(8): Make the "Too many authentication failures" message include
1610 the user, source address, port and protocol in a format similar to the
1611 authentication success / failure messages.
1612 - Use CLOCK_BOOTTIME in preference to CLOCK_MONOTONIC when it is
1613 available. It considers time spent suspended, thereby ensuring
1614 timeouts (e.g. for expiring agent keys) fire correctly (closes:
1615 #734553).
1616 - Use prctl() to prevent sftp-server from accessing
1617 /proc/self/{mem,maps}.
1618 * Restore TCP wrappers support, removed upstream in 6.7. It is true that
1619 dropping this reduces preauth attack surface in sshd. On the other
1620 hand, this support seems to be quite widely used, and abruptly dropping
1621 it (from the perspective of users who don't read openssh-unix-dev) could
1622 easily cause more serious problems in practice. It's not entirely clear
1623 what the right long-term answer for Debian is, but it at least probably
1624 doesn't involve dropping this feature shortly before a freeze.
1625 * Replace patch to disable OpenSSL version check with an updated version
1626 of Kurt Roeckx's patch from #732940 to just avoid checking the status
1627 field.
1628 * Build-depend on a new enough dpkg-dev for dpkg-buildflags, rather than
1629 simply a new enough dpkg.
1630 * Simplify debian/rules using /usr/share/dpkg/buildflags.mk.
1631 * Use Package-Type rather than XC-Package-Type, now that it is an official
1632 field.
1633 * Run a subset of the upstream regression test suite at package build
1634 time, and the rest of it under autopkgtest.

1818
1819 * New upstream release (http://www.openssh.com/txt/release-6.5,
1820 LP: #1275068):
1821 - ssh(1): Add support for client-side hostname canonicalisation using a
1822 set of DNS suffixes and rules in ssh_config(5). This allows
1823 unqualified names to be canonicalised to fully-qualified domain names
1824 to eliminate ambiguity when looking up keys in known_hosts or checking
1825 host certificate names (closes: #115286).
1826 * Switch to git; adjust Vcs-* fields.
1827 * Convert to git-dpm, and drop source package documentation associated
1828 with the old bzr/quilt patch handling workflow.
1829 * Drop ssh-vulnkey and the associated ssh/ssh-add/sshd integration code,
1830 leaving only basic configuration file compatibility, since it has been
1831 nearly six years since the original vulnerability and this code is not
1832 likely to be of much value any more (closes: #481853, #570651). See
1833 https://lists.debian.org/debian-devel/2013/09/msg00240.html for my full
1834 reasoning.
1835 * Add OpenPGP signature checking configuration to watch file (thanks,
1836 Daniel Kahn Gillmor; closes: #732441).
1837 * Add the pam_keyinit session module, to create a new session keyring on
1838 login (closes: #734816).
1839 * Incorporate default path changes from shadow 1:4.0.18.1-8, removing
1840 /usr/bin/X11 (closes: #644521).
1841 * Generate ED25519 host keys on fresh installations. Upgraders who wish
1842 to add such host keys should manually add 'HostKey
1843 /etc/ssh/ssh_host_ed25519_key' to /etc/ssh/sshd_config and run
1844 'ssh-keygen -q -f /etc/ssh/ssh_host_ed25519_key -N "" -t ed25519'.
1845 * Drop long-obsolete "SSH now uses protocol 2 by default" section from
1846 README.Debian.
1847 * Add systemd support (thanks, Sven Joachim; closes: #676830).

1862 - 6.3/6.3p1 (http://www.openssh.com/txt/release-6.3):
1863 + sftp(1): add support for resuming partial downloads using the
1864 "reget" command and on the sftp commandline or on the "get"
1865 commandline using the "-a" (append) option (closes: #158590).
1866 + ssh(1): add an "IgnoreUnknown" configuration option to selectively
1867 suppress errors arising from unknown configuration directives
1868 (closes: #436052).
1869 + sftp(1): update progressmeter when data is acknowledged, not when
1870 it's sent (partially addresses #708372).
1871 + ssh(1): do not fatally exit when attempting to cleanup multiplexing-
1872 created channels that are incompletely opened (closes: #651357).
1873 - 6.4/6.4p1 (http://www.openssh.com/txt/release-6.4):
1874 + CVE-2013-4548: sshd(8): fix a memory corruption problem triggered
1875 during rekeying when an AES-GCM cipher is selected (closes:
1876 #729029). Full details of the vulnerability are available at:
1877 http://www.openssh.com/txt/gcmrekey.adv
1878 * When running under Upstart, only consider the daemon started once it is
1879 ready to accept connections (by raising SIGSTOP at that point and using
1880 "expect stop").

1925
1926openssh (1:6.2p2-2) unstable; urgency=low
1927
1928 * Change start condition of Upstart job to be just the standard "runlevel
1929 [2345]", rather than "filesystem or runlevel [2345]"; the latter makes
1930 it unreasonably difficult to ensure that urandom starts before ssh, and
1931 is not really necessary since one of static-network-up and failsafe-boot
1932 is guaranteed to happen and will trigger entry to the default runlevel,
1933 and we don't care about ssh starting before the network (LP: #1098299).
1934 * Drop conffile handling for direct upgrades from pre-split ssh package;
1935 this was originally added in 1:4.3p2-7 / 1:4.3p2-8, and contained a
1936 truly ghastly hack around a misbehaviour in sarge's dpkg. Since this is
1937 now four Debian releases ago, we can afford to drop this and simplify
1938 the packaging.
1939 * Remove ssh/use_old_init_script, which was a workaround for a very old
1940 bug in /etc/init.d/ssh. If anyone has ignored this for >10 years then
1941 they aren't going to be convinced now (closes: #214182).
1942 * Remove support for upgrading directly from ssh-nonfree.
1943 * Remove lots of maintainer script support for direct upgrades from
1944 pre-etch (three releases before current stable).
1945 * Add #DEBHELPER# tokens to openssh-client.postinst and
1946 openssh-server.postinst.
1947 * Replace old manual conffile handling code with dpkg-maintscript-helper,
1948 via dh_installdeb.
1949 * Switch to new unified layout for Upstart jobs as documented in
1950 https://wiki.ubuntu.com/UpstartCompatibleInitScripts: the init script
1951 checks for a running Upstart, and we now let dh_installinit handle most
1952 of the heavy lifting in maintainer scripts. Ubuntu users should be
1953 essentially unaffected except that sshd may no longer start
1954 automatically in chroots if the running Upstart predates 0.9.0; but the
1955 main goal is simply not to break when openssh-server is installed in a
1956 chroot.
1957 * Remove the check for vulnerable host keys; this was first added five
1958 years ago, and everyone should have upgraded through a version that
1959 applied these checks by now. The ssh-vulnkey tool and the blacklisting
1960 support in sshd are still here, at least for the moment.
1961 * This removes the last of our uses of debconf (closes: #221531).
1962 * Use the pam_loginuid session module (thanks, Laurent Bigonville; closes:
1963 #677440, LP: #1067779).
1964 * Bracket our session stack with calls to pam_selinux close/open (thanks,
1965 Laurent Bigonville; closes: #679458).

1967 binary packages, as intended since 1:6.1p1-2.

2234 * New upstream release (http://www.openssh.com/txt/release-5.7):
2235 - Implement Elliptic Curve Cryptography modes for key exchange (ECDH)
2236 and host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA
2237 offer better performance than plain DH and DSA at the same equivalent
2238 symmetric key length, as well as much shorter keys.
2239 - sftp(1)/sftp-server(8): add a protocol extension to support a hard
2240 link operation. It is available through the "ln" command in the
2241 client. The old "ln" behaviour of creating a symlink is available
2242 using its "-s" option or through the preexisting "symlink" command.
2243 - scp(1): Add a new -3 option to scp: Copies between two remote hosts
2244 are transferred through the local host (closes: #508613).
2245 - ssh(1): "atomically" create the listening mux socket by binding it on
2246 a temporary name and then linking it into position after listen() has
2247 succeeded. This allows the mux clients to determine that the server
2248 socket is either ready or stale without races (closes: #454784).
2249 Stale server sockets are now automatically removed (closes: #523250).
2250 - ssh(1): install a SIGCHLD handler to reap expired child process
2251 (closes: #594687).
2252 - ssh(1)/ssh-agent(1): honour $TMPDIR for client xauth and ssh-agent
2253 temporary directories (closes: #357469, although only if you arrange
2254 for ssh-agent to actually see $TMPDIR since the setgid bit will cause
2255 it to be stripped off).
2256 * Update to current GSSAPI patch from
2257 http://www.sxw.org.uk/computing/patches/openssh-5.7p1-gsskex-all-20110125.patch:
2258 - Add GSSAPIServerIdentity option.
2259 * Generate ECDSA host keys on fresh installations. Upgraders who wish to
2260 add such host keys should manually add 'HostKey
2261 /etc/ssh/ssh_host_ecdsa_key' to /etc/ssh/sshd_config and run 'ssh-keygen
2262 -q -f /etc/ssh/ssh_host_ecdsa_key -N "" -t ecdsa'.
2263 * Build-depend on libssl-dev (>= 0.9.8g) to ensure sufficient ECC support.
2264 * Backport SELinux build fix from CVS.
2265 * Rearrange selinux-role.patch so that it links properly given this
2266 SELinux build fix.

2383
2384 * New upstream release (LP: #535029).
2385 - After a transition period of about 10 years, this release disables SSH
2386 protocol 1 by default. Clients and servers that need to use the
2387 legacy protocol must explicitly enable it in ssh_config / sshd_config
2388 or on the command-line.
2389 - Remove the libsectok/OpenSC-based smartcard code and add support for
2390 PKCS#11 tokens. This support is enabled by default in the Debian
2391 packaging, since it now doesn't involve additional library
2392 dependencies (closes: #231472, LP: #16918).
2393 - Add support for certificate authentication of users and hosts using a
2394 new, minimal OpenSSH certificate format (closes: #482806).
2395 - Added a 'netcat mode' to ssh(1): "ssh -W host:port ...".
2396 - Add the ability to revoke keys in sshd(8) and ssh(1). (For the Debian
2397 package, this overlaps with the key blacklisting facility added in
2398 openssh 1:4.7p1-9, but with different file formats and slightly
2399 different scopes; for the moment, I've roughly merged the two.)
2400 - Various multiplexing improvements, including support for requesting
2401 port-forwardings via the multiplex protocol (closes: #360151).
2402 - Allow setting an explicit umask on the sftp-server(8) commandline to
2403 override whatever default the user has (closes: #496843).
2404 - Many sftp client improvements, including tab-completion, more options,
2405 and recursive transfer support for get/put (LP: #33378). The old
2406 mget/mput commands never worked properly and have been removed
2407 (closes: #270399, #428082).
2408 - Do not prompt for a passphrase if we fail to open a keyfile, and log
2409 the reason why the open failed to debug (closes: #431538).
2410 - Prevent sftp from crashing when given a "-" without a command. Also,
2411 allow whitespace to follow a "-" (closes: #531561).
2412
2413 * Fix 'debian/rules quilt-setup' to avoid writing .orig files if some
2414 patches apply with offsets.
2415 * Include debian/ssh-askpass-gnome.png in the Debian tarball now that
2416 we're using a source format that permits this, rather than messing
2417 around with uudecode.
2418 * Drop compatibility with the old gssapi mechanism used in ssh-krb5 <<
2419 3.8.1p1-1. Simon Wilkinson refused this patch since the old gssapi
2420 mechanism was removed due to a serious security hole, and since these
2421 versions of ssh-krb5 are no longer security-supported by Debian I don't
2422 think there's any point keeping client compatibility for them.
2423 * Fix substitution of ETC_PAM_D_SSH, following the rename in 1:4.7p1-4.
2424 * Hardcode the location of xauth to /usr/bin/xauth rather than
2425 /usr/bin/X11/xauth (thanks, Aron Griffis; closes: #575725, LP: #8440).
2426 xauth no longer depends on x11-common, so we're no longer guaranteed to
2427 have the /usr/bin/X11 symlink available. I was taking advantage of the
2428 /usr/bin/X11 symlink to smooth X's move to /usr/bin, but this is far
2429 enough in the past now that it's probably safe to just use /usr/bin.
2430 * Remove SSHD_OOM_ADJUST configuration. sshd now unconditionally makes
2431 itself non-OOM-killable, and doesn't require configuration to avoid log
2432 spam in virtualisation containers (closes: #555625).
2433 * Drop Debian-specific removal of OpenSSL version check. Upstream ignores
2434 the two patchlevel nybbles now, which is sufficient to address the
2435 original reason this change was introduced, and it appears that any
2436 change in the major/minor/fix nybbles would involve a new libssl package
2437 name. (We'd still lose if the status nybble were ever changed, but that
2438 would mean somebody had packaged a development/beta version rather than
2439 a proper release, which doesn't appear to be normal practice.)
2440 * Drop most of our "LogLevel SILENT" (-qq) patch. This was originally
2441 introduced to match the behaviour of non-free SSH, in which -q does not
2442 suppress fatal errors, but matching the behaviour of OpenSSH upstream is
2443 much more important nowadays. We no longer document that -q does not
2444 suppress fatal errors (closes: #280609). Migrate "LogLevel SILENT" to
2445 "LogLevel QUIET" in sshd_config on upgrade.
2446 * Policy version 3.8.4:

2518 - Change the default cipher order to prefer the AES CTR modes and the
2519 revised "arcfour256" mode to CBC mode ciphers that are susceptible to
2520 CPNI-957037 "Plaintext Recovery Attack Against SSH".
2521 - Add countermeasures to mitigate CPNI-957037-style attacks against the
2522 SSH protocol's use of CBC-mode ciphers. Upon detection of an invalid
2523 packet length or Message Authentication Code, ssh/sshd will continue
2524 reading up to the maximum supported packet length rather than
2525 immediately terminating the connection. This eliminates most of the
2526 known differences in behaviour that leaked information about the
2527 plaintext of injected data which formed the basis of this attack
2528 (closes: #506115, LP: #379329).

2673
2674 * New upstream release (closes: #474301). Important changes not previously
2675 backported to 4.7p1:
2676 - 4.9/4.9p1 (http://www.openssh.com/txt/release-4.9):
2677 + Added chroot(2) support for sshd(8), controlled by a new option
2678 "ChrootDirectory" (closes: #139047, LP: #24777).
2679 + Linked sftp-server(8) into sshd(8). The internal sftp server is used
2680 when the command "internal-sftp" is specified in a Subsystem or
2681 ForceCommand declaration. When used with ChrootDirectory, the
2682 internal sftp server requires no special configuration of files
2683 inside the chroot environment.
2684 + Added a protocol extension method "posix-rename@openssh.com" for
2685 sftp-server(8) to perform POSIX atomic rename() operations; sftp(1)
2686 prefers this if available (closes: #308561).
2687 + Removed the fixed limit of 100 file handles in sftp-server(8).
2688 + ssh(8) will now skip generation of SSH protocol 1 ephemeral server
2689 keys when in inetd mode and protocol 2 connections are negotiated.
2690 This speeds up protocol 2 connections to inetd-mode servers that
2691 also allow Protocol 1.
2692 + Accept the PermitRootLogin directive in a sshd_config(5) Match
2693 block. Allows for, e.g. permitting root only from the local network.
2694 + Reworked sftp(1) argument splitting and escaping to be more
2695 internally consistent (i.e. between sftp commands) and more
2696 consistent with sh(1). Please note that this will change the
2697 interpretation of some quoted strings, especially those with
2698 embedded backslash escape sequences.
2699 + Support "Banner=none" in sshd_config(5) to disable sending of a
2700 pre-login banner (e.g. in a Match block).
2701 + ssh(1) ProxyCommands are now executed with $SHELL rather than
2702 /bin/sh.
2703 + ssh(1)'s ConnectTimeout option is now applied to both the TCP
2704 connection and the SSH banner exchange (previously it just covered
2705 the TCP connection). This allows callers of ssh(1) to better detect
2706 and deal with stuck servers that accept a TCP connection but don't
2707 progress the protocol, and also makes ConnectTimeout useful for
2708 connections via a ProxyCommand.
2709 + scp(1) incorrectly reported "stalled" on slow copies (closes:
2710 #140828).
2711 + scp(1) date underflow for timestamps before epoch.
2712 + ssh(1) used the obsolete SIG DNS RRtype for host keys in DNS,
2713 instead of the current standard RRSIG.
2714 + Correctly drain ACKs when a sftp(1) upload write fails midway,
2715 avoids a fatal() exit from what should be a recoverable condition.
2716 + Fixed ssh-keygen(1) selective host key hashing (i.e. "ssh-keygen -HF
2717 hostname") to not include any IP address in the data to be hashed.
2718 + Make ssh(1) skip listening on the IPv6 wildcard address when a
2719 binding address of 0.0.0.0 is used against an old SSH server that
2720 does not support the RFC4254 syntax for wildcard bind addresses.
2721 + Enable IPV6_V6ONLY socket option on sshd(8) listen socket, as is
2722 already done for X11/TCP forwarding sockets (closes: #439661).
2723 + Fix FD leak that could hang a ssh(1) connection multiplexing master.
2724 + Make ssh(1) -q option documentation consistent with reality.
2725 + Fixed sshd(8) PAM support not calling pam_session_close(), or
2726 failing to call it with root privileges (closes: #372680).
2727 + Fix activation of OpenSSL engine support when requested in configure
2728 (LP: #119295).
2729 + Cache SELinux status earlier so we know if it's enabled after a
2730 chroot (LP: #237557).
2731 - 5.1/5.1p1 (http://www.openssh.com/txt/release-5.1):
2732 + Introduce experimental SSH Fingerprint ASCII Visualisation to ssh(1)
2733 and ssh-keygen(1). Visual fingerprint display is controlled by a new
2734 ssh_config(5) option "VisualHostKey". The intent is to render SSH
2735 host keys in a visual form that is amenable to easy recall and
2736 rejection of changed host keys.
2737 + sshd_config(5) now supports CIDR address/masklen matching in "Match
2738 address" blocks, with a fallback to classic wildcard matching.
2739 + sshd(8) now supports CIDR matching in ~/.ssh/authorized_keys
2740 from="..." restrictions, also with a fallback to classic wildcard
2741 matching.
2742 + Added an extended test mode (-T) to sshd(8) to request that it write
2743 its effective configuration to stdout and exit. Extended test mode
2744 also supports the specification of connection parameters (username,
2745 source address and hostname) to test the application of
2746 sshd_config(5) Match rules.
2747 + ssh(1) now prints the number of bytes transferred and the overall
2748 connection throughput for SSH protocol 2 sessions when in verbose
2749 mode (previously these statistics were displayed for protocol 1
2750 connections only).
2751 + sftp-server(8) now supports extension methods statvfs@openssh.com
2752 and fstatvfs@openssh.com that implement statvfs(2)-like operations.
2753 + sftp(1) now has a "df" command to the sftp client that uses the
2754 statvfs@openssh.com to produce a df(1)-like display of filesystem
2755 space and inode utilisation (requires statvfs@openssh.com support on
2756 the server).
2757 + Added a MaxSessions option to sshd_config(5) to allow control of the
2758 number of multiplexed sessions supported over a single TCP
2759 connection. This allows increasing the number of allowed sessions
2760 above the previous default of 10, disabling connection multiplexing
2761 (MaxSessions=1) or disallowing login/shell/subsystem sessions
2762 entirely (MaxSessions=0).
2763 + Added a no-more-sessions@openssh.com global request extension that
2764 is sent from ssh(1) to sshd(8) when the client knows that it will
2765 never request another session (i.e. when session multiplexing is
2766 disabled). This allows a server to disallow further session requests
2767 and terminate the session in cases where the client has been
2768 hijacked.
2769 + ssh-keygen(1) now supports the use of the -l option in combination
2770 with -F to search for a host in ~/.ssh/known_hosts and display its
2771 fingerprint.
2772 + ssh-keyscan(1) now defaults to "rsa" (protocol 2) keys, instead of
2773 "rsa1" (LP: #129794).
2774 + Added an AllowAgentForwarding option to sshd_config(8) to control
2775 whether authentication agent forwarding is permitted. Note that this
2776 is a loose control, as a client may install their own unofficial
2777 forwarder.
2778 + ssh(1) and sshd(8): avoid unnecessary malloc/copy/free when
2779 receiving network data, resulting in a ~10% speedup.
2780 + ssh(1) and sshd(8) will now try additional addresses when connecting
2781 to a port forward destination whose DNS name resolves to more than
2782 one address. The previous behaviour was to try the only first
2783 address and give up if that failed.
2784 + ssh(1) and sshd(8) now support signalling that channels are
2785 half-closed for writing, through a channel protocol extension
2786 notification "eow@openssh.com". This allows propagation of closed
2787 file descriptors, so that commands such as "ssh -2 localhost od
2788 /bin/ls | true" do not send unnecessary data over the wire.
2789 + sshd(8): increased the default size of ssh protocol 1 ephemeral keys
2790 from 768 to 1024 bits.
2791 + When ssh(1) has been requested to fork after authentication ("ssh
2792 -f") with ExitOnForwardFailure enabled, delay the fork until after
2793 replies for any -R forwards have been seen. Allows for robust
2794 detection of -R forward failure when using -f.
2795 + "Match group" blocks in sshd_config(5) now support negation of
2796 groups. E.g. "Match group staff,!guests".
2797 + sftp(1) and sftp-server(8) now allow chmod-like operations to set
2798 set[ug]id/sticky bits.
2799 + The MaxAuthTries option is now permitted in sshd_config(5) match
2800 blocks.
2801 + Multiplexed ssh(1) sessions now support a subset of the ~ escapes
2802 that are available to a primary connection.
2803 + ssh(1) connection multiplexing will now fall back to creating a new
2804 connection in most error cases (closes: #352830).
2805 + Make ssh(1) deal more gracefully with channel requests that fail.
2806 Previously it would optimistically assume that requests would always
2807 succeed, which could cause hangs if they did not (e.g. when the
2808 server runs out of file descriptors).
2809 + ssh(1) now reports multiplexing errors via the multiplex slave's
2810 stderr where possible (subject to LogLevel in the mux master).
2811 + Fixed an UMAC alignment problem that manifested on Itanium
2812 platforms.
2813 * Remove our local version of moduli(5) now that there's one upstream.
2814 * Say "GTK+" rather than "GTK" in ssh-askpass-gnome's description.
2815 * Add lintian overrides for empty /usr/share/doc/openssh-client
2816 directories in openssh-server and ssh (necessary due to being symlink
2817 targets).
2818 * Merge from Ubuntu:
2819 - Add 'status' action to openssh-server init script, requiring lsb-base
2820 (>= 3.2-13) (thanks, Dustin Kirkland).

3054 * New upstream release (closes: #453367).
3055 - CVE-2007-4752: Prevent ssh(1) from using a trusted X11 cookie if
3056 creation of an untrusted cookie fails; found and fixed by Jan Pechanec
3057 (closes: #444738).
3058 - sshd(8) in new installations defaults to SSH Protocol 2 only. Existing
3059 installations are unchanged.
3060 - The SSH channel window size has been increased, and both ssh(1)
3061 sshd(8) now send window updates more aggressively. These improves
3062 performance on high-BDP (Bandwidth Delay Product) networks.
3063 - ssh(1) and sshd(8) now preserve MAC contexts between packets, which
3064 saves 2 hash calls per packet and results in 12-16% speedup for
3065 arcfour256/hmac-md5.
3066 - A new MAC algorithm has been added, UMAC-64 (RFC4418) as
3067 "umac-64@openssh.com". UMAC-64 has been measured to be approximately
3068 20% faster than HMAC-MD5.
3069 - Failure to establish a ssh(1) TunnelForward is now treated as a fatal
3070 error when the ExitOnForwardFailure option is set.
3071 - ssh(1) returns a sensible exit status if the control master goes away
3072 without passing the full exit status.
3073 - When using a ProxyCommand in ssh(1), set the outgoing hostname with
3074 gethostname(2), allowing hostbased authentication to work.
3075 - Make scp(1) skip FIFOs rather than hanging (closes: #246774).
3076 - Encode non-printing characters in scp(1) filenames. These could cause
3077 copies to be aborted with a "protocol error".
3078 - Handle SIGINT in sshd(8) privilege separation child process to ensure
3079 that wtmp and lastlog records are correctly updated.
3080 - Report GSSAPI mechanism in errors, for libraries that support multiple
3081 mechanisms.
3082 - Improve documentation for ssh-add(1)'s -d option.
3083 - Rearrange and tidy GSSAPI code, removing server-only code being linked
3084 into the client.
3085 - Delay execution of ssh(1)'s LocalCommand until after all forwardings
3086 have been established.
3087 - In scp(1), do not truncate non-regular files.
3088 - Improve exit message from ControlMaster clients.
3089 - Prevent sftp-server(8) from reading until it runs out of buffer space,
3090 whereupon it would exit with a fatal error (closes: #365541).
3091 - pam_end() was not being called if authentication failed
3092 (closes: #405041).
3093 - Manual page datestamps updated (closes: #433181).
3094 * Install the OpenSSH FAQ in /usr/share/doc/openssh-client.

3204
3205 * New upstream release (closes: #395507, #397961, #420035). Important
3206 changes not previously backported to 4.3p2:
3207 - 4.4/4.4p1 (http://www.openssh.com/txt/release-4.4):
3208 + On portable OpenSSH, fix a GSSAPI authentication abort that could be
3209 used to determine the validity of usernames on some platforms.
3210 + Implemented conditional configuration in sshd_config(5) using the
3211 "Match" directive. This allows some configuration options to be
3212 selectively overridden if specific criteria (based on user, group,
3213 hostname and/or address) are met. So far a useful subset of
3214 post-authentication options are supported and more are expected to
3215 be added in future releases.
3216 + Add support for Diffie-Hellman group exchange key agreement with a
3217 final hash of SHA256.
3218 + Added a "ForceCommand" directive to sshd_config(5). Similar to the
3219 command="..." option accepted in ~/.ssh/authorized_keys, this forces
3220 the execution of the specified command regardless of what the user
3221 requested. This is very useful in conjunction with the new "Match"
3222 option.
3223 + Add a "PermitOpen" directive to sshd_config(5). This mirrors the
3224 permitopen="..." authorized_keys option, allowing fine-grained
3225 control over the port-forwardings that a user is allowed to
3226 establish.
3227 + Add optional logging of transactions to sftp-server(8).
3228 + ssh(1) will now record port numbers for hosts stored in
3229 ~/.ssh/known_hosts when a non-standard port has been requested
3230 (closes: #50612).
3231 + Add an "ExitOnForwardFailure" option to cause ssh(1) to exit (with a
3232 non-zero exit code) when requested port forwardings could not be
3233 established.
3234 + Extend sshd_config(5) "SubSystem" declarations to allow the
3235 specification of command-line arguments.
3236 + Replacement of all integer overflow susceptible invocations of
3237 malloc(3) and realloc(3) with overflow-checking equivalents.
3238 + Many manpage fixes and improvements.
3239 + Add optional support for OpenSSL hardware accelerators (engines),
3240 enabled using the --with-ssl-engine configure option.
3241 + Tokens in configuration files may be double-quoted in order to
3242 contain spaces (closes: #319639).
3243 + Move a debug() call out of a SIGCHLD handler, fixing a hang when the
3244 session exits very quickly (closes: #307890).
3245 + Fix some incorrect buffer allocation calculations (closes: #410599).
3246 + ssh-add doesn't ask for a passphrase if key file permissions are too
3247 liberal (closes: #103677).
3248 + Likewise, ssh doesn't ask either (closes: #99675).
3249 - 4.6/4.6p1 (http://www.openssh.com/txt/release-4.6):
3250 + sshd now allows the enabling and disabling of authentication methods
3251 on a per user, group, host and network basis via the Match directive
3252 in sshd_config.
3253 + Fixed an inconsistent check for a terminal when displaying scp
3254 progress meter (closes: #257524).
3255 + Fix "hang on exit" when background processes are running at the time
3256 of exit on a ttyful/login session (closes: #88337).
3257 * Update to current GSSAPI patch from
3258 http://www.sxw.org.uk/computing/patches/openssh-4.6p1-gsskex-20070312.patch;
3259 install ChangeLog.gssapi.
3260 * Build the .deb --with-ssl-engine (closes: #408027, LP: #119295).
3261 * Use LSB functions in init scripts, and add an LSB-style header (partly
3262 from Ubuntu and partly thanks to Christian Perrier; closes: #389038).
3263 * Move init script start links to S16, move rc1 stop link to K84, and
3264 remove rc0 and rc6 stop links altogether (the last part from Ubuntu;
3265 closes: #122188).
3266 * Emit a slightly more informative message from the init script if
3267 /dev/null has somehow become not a character device (closes: #369964).
3268 * Belatedly build-depend on zlib1g-dev (>= 1:1.2.3-1) (closes: #333447).
3269 * Merge from Ubuntu:
3270 - Build position-independent executables (only for debs, not for udebs)
3271 to take advantage of address space layout randomisation.
3272 - If building on Ubuntu, add /sbin, /usr/sbin, and /usr/local/sbin to
3273 the default path.
3274 * Use ${binary:Version} rather than ${Source-Version} in openssh-server ->
3275 openssh-client dependency.

3352 * It turns out that the people who told me that removing a conffile in the
3353 preinst was sufficient to have dpkg replace it without prompting when
3354 moving a conffile between packages were very much mistaken. As far as I
3355 can tell, the only way to do this reliably is to write out the desired
3356 new text of the conffile in the preinst. This is gross, and requires
3357 shipping the text of all conffiles in the preinst too, but there's
3358 nothing for it. Fortunately this nonsense is only required for smooth

3475 * New upstream release (closes: #361032).
3476 - CVE-2006-0225: scp (as does rcp, on which it is based) invoked a
3477 subshell to perform local to local, and remote to remote copy
3478 operations. This subshell exposed filenames to shell expansion twice;
3479 allowing a local attacker to create filenames containing shell
3480 metacharacters that, if matched by a wildcard, could lead to execution
3481 of attacker-specified commands with the privilege of the user running
3482 scp (closes: #349645).
3483 - Add support for tunneling arbitrary network packets over a connection
3484 between an OpenSSH client and server via tun(4) virtual network
3485 interfaces. This allows the use of OpenSSH (4.3+) to create a true VPN
3486 between the client and server providing real network connectivity at
3487 layer 2 or 3. This feature is experimental.
3488 - Reduce default key length for new DSA keys generated by ssh-keygen
3489 back to 1024 bits. DSA is not specified for longer lengths and does
3490 not fully benefit from simply making keys longer. As per FIPS 186-2
3491 Change Notice 1, ssh-keygen will refuse to generate a new DSA key
3492 smaller or larger than 1024 bits.
3493 - Fixed X forwarding failing to start when the X11 client is executed in
3494 background at the time of session exit.
3495 - Change ssh-keygen to generate a protocol 2 RSA key when invoked
3496 without arguments (closes: #114894).
3497 - Fix timing variance for valid vs. invalid accounts when attempting
3498 Kerberos authentication.
3499 - Ensure that ssh always returns code 255 on internal error
3500 (closes: #259865).
3501 - Cleanup wtmp files on SIGTERM when not using privsep.
3502 - Set SO_REUSEADDR on X11 listeners to avoid problems caused by
3503 lingering sockets from previous session (X11 applications can
3504 sometimes not connect to 127.0.0.1:60xx) (closes:
3505 https://launchpad.net/bugs/25528).
3506 - Ensure that fds 0, 1 and 2 are always attached in all programs, by
3507 duping /dev/null to them if necessary.
3508 - Xauth list invocation had bogus "." argument.
3509 - Remove internal assumptions on key exchange hash algorithm and output
3510 length, preparing OpenSSH for KEX methods with alternate hashes.
3511 - Ignore junk sent by a server before it sends the "SSH-" banner.
3512 - Many manual page improvements.
3513 - Lots of cleanups, including fixes to memory leaks on error paths and
3514 possible crashes.
3515 * Update to current GSSAPI patch from
3516 http://www.sxw.org.uk/computing/patches/openssh-4.3p2-gsskex-20060223.patch
3517 (closes: #352042).

3519 * Restore pam_nologin to /etc/pam.d/ssh; sshd no longer checks this itself
3520 when PAM is enabled, but relies on PAM to do it.

3522 (closes: #349896).
3523 * Rephrase ssh/new_config and ssh/encrypted_host_key_but_no_keygen debconf

3626 credentials. This code is only built in openssh-krb5, not openssh, but
3627 I mention the CVE reference here anyway for completeness.
3628 - Add a new compression method ("Compression delayed") that delays zlib
3629 compression until after authentication, eliminating the risk of zlib
3630 vulnerabilities being exploited by unauthenticated users. Note that
3631 users of OpenSSH versions earlier than 3.5 will need to disable

3721 this should edit sshd_config instead (closes: #147212).
3722 * Since ssh-keysign isn't used by default (you need to set
3723 EnableSSHKeysign to "yes" in /etc/ssh/ssh_config), having a debconf
3724 question to ask whether it should be setuid is overkill, and the
3725 question text had got out of date anyway. Remove this question, ship
3726 ssh-keysign setuid in openssh-client.deb, and set a statoverride if the
3727 debconf question was previously set to false.
3728 * Add lintian overrides for the above (setuid-binary,
3729 no-debconf-templates).
3730 * Fix picky lintian errors about slogin symlinks.
3731 * Fix DEB_HOST_ARCH_OS/DEB_HOST_GNU_SYSTEM compatibility handling.
3732 * Apply Linux 2.2 workaround (see #239999) only on Linux.

3739 - Normalise socket addresses returned by get_remote_hostname(), fixing
3740 4-in-6 mapping issues with AllowUsers et al (closes: #192234).
3741 * Take upstream's hint and disable the unsupported USE_POSIX_THREADS
3742 (closes: #295757, #308868, and possibly others; may open other bugs).
3743 Use PAM password authentication to avoid #278394. In future I may
3744 provide two sets of binaries built with and without this option, since
3745 it seems I can't win.
3746 * Disable ChallengeResponseAuthentication in new installations, returning
3747 to PasswordAuthentication by default, since it now supports PAM and
3748 apparently works better with a non-threaded sshd (closes: #247521).
3749 * openssh-server Suggests: rssh (closes: #233012).
3750 * Change libexecdir to /usr/lib/openssh, and fix up various alternatives
3751 and configuration files to match (closes: #87900, #151321).

3760 - Port-forwarding specifications now take optional bind addresses, and
3761 the server allows client-specified bind addresses for remote port
3762 forwardings when configured with "GatewayPorts clientspecified"
3763 (closes: #87253, #192206).
3764 - ssh and ssh-keyscan now support hashing of known_hosts files for
3765 improved privacy (CAN-2005-2666). ssh-keygen has new options for
3766 managing known_hosts files, which understand hashing.
3767 - sftp supports command history and editing support using libedit
3768 (closes: #287013).
3769 - Have scp and sftp wait for the spawned ssh to exit before they exit
3770 themselves, allowing ssh to restore terminal modes (closes: #257130).
3771 - Improved the handling of bad data in authorized_keys files,
3772 eliminating fatal errors on corrupt or very large keys; e.g. linefeeds
3773 in keys only produce errors in auth.log now (closes: #220726).
3774 - Add "command mode" to ssh connection multiplexing (closes: #303452).
3775 - Mention $HOME/.hushlogin in sshd(8) FILES section (closes: #163933).
3776 * Make gnome-ssh-askpass stay above other windows (thanks, Liyang HU;
3777 closes: #296487).
3778 * Remove obsolete and unnecessary ssh/forward_warning debconf note.
3779 * Hurd build fixes (although sshd still doesn't work):
3780 - Restore X forwarding fix from #102991, lost somewhere along the way.
3781 - Link with -lcrypt.
3782 - Link with -lpthread rather than -pthread.
3783 - Don't build ssh-askpass-gnome on the Hurd, until GNOME is available to
3784 satisfy build-dependencies.
3785 * Drop workaround for #242462 on amd64; it's been fixed properly upstream.
3786 * Enable HashKnownHosts by default. This only affects new entries; use
3787 'ssh-keygen -H' to convert an entire known_hosts file to hashed format.
3788 * Note in ssh_config(5) that the SetupTimeOut option is Debian-specific
3789 (closes: #307069).
3790 * debconf template translations:
3791 - Update Czech (thanks, Miroslav Kure; closes: #298744).

3900 common functionality; it didn't seem worth creating yet another package
3901 for this. openssh-client is priority standard, openssh-server optional.
3902 * New transitional ssh package, priority optional, depending on
3903 openssh-client and openssh-server. May be removed once nothing depends
3904 on it.
3905 * When upgrading from ssh to openssh-{client,server}, it's very difficult
3906 for the maintainer scripts to find out what version we're upgrading from
3907 without dodgy dpkg hackery. I've therefore taken the opportunity to move
3908 a couple of debconf notes into NEWS files, namely ssh/ssh2_keys_merged
3909 and ssh/user_environment_tell.
3910 * Add a heuristic to try to make sure the sshd_config upgrade to >= 3.7
3911 happens even though we don't know what version we're upgrading from.
3912 * Remove /etc/ssh/sshd_not_to_be_run on purge of openssh-server. For now
3913 (until sarge+2) it's still honoured to avoid breaking existing
3914 configurations, but the right approach is now to remove the
3915 openssh-server package if you don't want to run the server. Add a NEWS

4102 unconditionally in newly generated sshd_config files (closes: #228838).
4103 * ServerAliveInterval implemented upstream, so ProtocolKeepAlives is now a
4104 compatibility alias. The semantics differ slightly, though; see
4105 ssh_config(5) for details.
4106 * Implement SSH1 support for ServerAliveInterval using SSH_MSG_IGNORE. As
4107 documented in ssh_config(5), it's not as good as the SSH2 version.
4108 * Remove -fno-builtin-log, -DHAVE_MMAP_ANON_SHARED, and
4109 -D__FILE_OFFSET_BITS=64 compiler options, which are no longer necessary.
4110 * Update config.guess and config.sub from autotools-dev 20040105.1.
4111 * Darren Tucker:
4112 - Reset signal status when starting pam auth thread, prevent hanging
4113 during PAM keyboard-interactive authentications.
4114 - Fix a non-security-critical segfault in PAM authentication.
4115 * Add debconf template translations:
4116 - Greek (thanks, Konstantinos Margaritis; closes: #232843).
4117 - Italian (thanks, Renato Gini; closes: #234777).

4281 the whole thing, and remove the directory if that leaves it empty

4283 * ssh has depended on debconf for some time now with no complaints, so:
4284 - Simplify the postinst by relying on debconf being present. (The absent
4285 case was buggy anyway.)
4286 - Get rid of "if you have not installed debconf" text in README.Debian,
4287 and generally update the "/usr/bin/ssh not SUID" entry.
4288 * More README.Debian work:
4289 - Reorganize into "UPGRADE ISSUES" and "OTHER ISSUES", in an effort to
4290 make it easier for people to find the former. The upgrade issues
4291 should probably be sorted by version somehow.
4292 - Document X11UseLocalhost under "X11 Forwarding" (closes: #150913).

4341 * Find out whether /etc/ssh/sshd_not_to_be_run exists and set the debconf
4342 question's default using that information, rather than using debconf as
4343 a registry. Other solutions may be better in the long run, but this is
4344 at least correct (thanks, Matthew Woodcraft; closes: #84725).
4345 * Stop using pam_lastlog, as it doesn't currently work well as a session
4346 module when privilege separation is enabled; it can usually read
4347 /var/log/lastlog but can't write to it. Instead, just use sshd's
4348 built-in support, already enabled by default (closes: #151297, #169938).

4408 - ssh-agent is installed setgid to prevent ptrace() attacks. The group
4409 actually doesn't matter, as it drops privileges immediately, but to

47 This is the portable version of OpenSSH, a free implementation of
48 the Secure Shell protocol as specified by the IETF secsh working
49 group.
50 .
51 Ssh (Secure Shell) is a program for logging into a remote machine
52 and for executing commands on a remote machine.
53 It provides secure encrypted communications between two untrusted
54 hosts over an insecure network. X11 connections and arbitrary TCP/IP
55 ports can also be forwarded over the secure channel.
56 It can be used to provide applications with a secure communication
57 channel.
58 .
59 This package provides the ssh, scp and sftp clients, the ssh-agent
60 and ssh-add programs to make public key authentication more convenient,
61 and the ssh-keygen, ssh-keyscan, ssh-copy-id and ssh-argv0 utilities.
62 .
63 In some countries it may be illegal to use any encryption at all
64 without a special permit.
65 .
66 ssh replaces the insecure rsh, rcp and rlogin programs, which are
67 obsolete for most purposes.

145 This package provides the SFTP server module for the SSH server. It
146 is needed if you want to access your SSH server with SFTP. The SFTP
147 server module also works with other SSH daemons like dropbear.
148 .

150 protocol described in:
151 .
152 http://www.openssh.com/txt/draft-ietf-secsh-filexfer-02.txt

6 The overall licence of the OpenSSH upstream code amounts to BSD-3-clause or
7 various less restrictive licences, with the additional restrictions that
8 derived versions must be clearly marked as such and that if derived works
9 are incompatible with the RFC-specified protocol then they must be called
10 by a name other than "ssh" or "Secure Shell".

79OpenSSH provides end-to-end encrypted replacement of applications such as
80telnet, rlogin, and ftp.
81Unlike these legacy applications, OpenSSH never passes anything
82(including username and password) over the wire in unencrypted form, and
83provides host authentication, to verify that you really are talking to
84the system that you think you are and that no one else can take over
85that session.
86
87<p>
88The OpenSSH suite includes the
89<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1">ssh(1)</a>
90program which replaces rlogin and telnet, and
91<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&amp;sektion=1">scp(1)</a>
92which replaces
93<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=rcp&amp;sektion=1">rcp(1)</a> and
94<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ftp&amp;sektion=1">ftp(1)</a>.
95OpenSSH has also added
96<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&amp;sektion=1">sftp(1)</a> and
97<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp-server&amp;sektion=8">sftp-server(8)</a>
98which implement an easier solution for file-transfer. This is based upon the
99<a href="http://www.openssh.com/txt/draft-ietf-secsh-filexfer-02.txt">secsh-filexfer</a> IETF draft.
100
101
102<p><strong>OpenSSH consists of a number of programs.</strong>
103
104<ul>
105<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&amp;sektion=8">sshd(8)</a> - Server program run on the server machine. This listens for connections from client machines, and whenever it receives a connection, it performs authentication and starts serving the client.
106Its behaviour is controlled by the config file <i><a
107href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&amp;sektion=5">
108sshd_config(5)</a></i>.
109<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1">ssh(1)</a> - This is the client program used to log into another machine or to execute commands on the other machine. <i>slogin</i> is another name for this program.
110Its behaviour is controlled by the global config file <i><a
111href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh_config&amp;sektion=5">
112ssh_config(5)</a></i> and individual users' <i>$HOME/.ssh/config</i> files.
113<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&amp;sektion=1">scp(1)</a> - Securely copies files from one machine to another.
114<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keygen&amp;sektion=1">ssh-keygen(1)</a> - Used to create Pubkey Authentication (RSA or DSA) keys (host keys and user authentication keys).
115<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-agent&amp;sektion=1">ssh-agent(1)</a> - Authentication agent. This can be used to hold RSA keys for authentication.
116<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-add&amp;sektion=1">ssh-add(1)</a> - Used to register new keys with the agent.
117<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp-server&amp;sektion=8">sftp-server(8)</a> - SFTP server subsystem.
118<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&amp;sektion=1">sftp(1)</a> - Secure file transfer program.
119<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keyscan&amp;sektion=1">ssh-keyscan(1)</a> - gather ssh public keys.
120<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keysign&amp;sektion=8">ssh-keysign(8)</a> - ssh helper program for hostbased authentication.
121</ul>
122
123<h3>Downloading</h3>
124
125<p>
126The most recent version of OpenSSH is included with the current
127distribution of <a href="http://www.openbsd.org/">OpenBSD</a>, and
128installed as part of a basic install.
129
130<p>
131Today, most other operating systems include some version of OpenSSH
132(often re-badged or privately labeled), so most users can immediately
133use it.
134However, sometimes the included versions are quite old, and missing
135features of the current release of OpenSSH, and you may wish to install
136the current version, or install it on one of the few OSs that lacked it,
137and where the OS publisher does not make a modern version available.
138You may also wish to use OpenSSH on your embedded application.
139
140<p>
141Non-OpenBSD users will want to download, compile and install the
142multi-platform <a href="http://www.openssh.com/portable.html">Portable</a> distribution from a
143<a href="http://www.openssh.com/portable.html#mirrors">mirror</a> near you.
144
145
146<h2><a name= "1.2">1.2 - Why should it be used?</a></h2>
147
148<p>
149OpenSSH is a suite of tools to help secure your network
150connections. Here is a list of features:
151
152
153<ul>
154 <li>Strong authentication. Closes several security holes (e.g., IP, routing, and DNS spoofing).
155 <li>Improved privacy. All communications are automatically and transparently encrypted.
156 <li>Secure X11 sessions. The program automatically sets DISPLAY on the server machine, and forwards any X11 connections over the secure channel.
157 <li>Arbitrary TCP/IP ports can be redirected through the encrypted channel in both directions (e.g., for e-cash transactions).
158 <li>No retraining needed for normal users.
159 <li>Never trusts the network. Minimal trust on the remote side of the connection. Minimal trust on domain name servers. Pure RSA authentication never trusts anything but the private key.
160 <li>Client RSA-authenticates the server machine in the beginning of every connection to prevent trojan horses (by routing or DNS spoofing) and man-in-the-middle attacks, and the server RSA-authenticates the client machine before accepting <i>.rhosts</i> or <i>/etc/hosts.equiv</i> authentication (to prevent DNS, routing, or IP-spoofing).
161 <li>Host authentication key distribution can be centrally by the administration, automatically when the first connection is made to a machine.
162 <li>Any user can create any number of user authentication RSA keys for his/her own use.
163 <li>The server program has its own server RSA key which is automatically regenerated every hour.
164 <li>An authentication agent, running in the user's laptop or local workstation, can be used to hold the user's RSA authentication keys.
165 <li>The software can be installed and used (with restricted functionality) even without root privileges.
166 <li>The client is customizable in system-wide and per-user configuration files.
167 <li>Optional compression of all data with gzip (including forwarded X11 and TCP/IP port data), which may result in significant speedups on slow connections.
168 <li>Complete replacement for rlogin, rsh, and rcp.
169</ul>
170
171<p>
172Currently, almost all communications in computer networks are done
173without encryption. As a consequence, anyone who has access to any
174machine connected to the network can listen in on any communication.
175This is being done by hackers, curious administrators, employers,
176criminals, industrial spies, and governments. Some networks leak off
177enough electromagnetic radiation that data may be captured even from a
178distance.
179
180
181<p>
182When you log in, your password goes in the network in plain
183text. Thus, any listener can then use your account to do any evil he
184likes. Many incidents have been encountered worldwide where crackers
185have started programs on workstations without the owner's knowledge
186just to listen to the network and collect passwords. Programs for
187doing this are available on the Internet, or can be built by a
188competent programmer in a few hours.
189
190
191<p>
192Businesses have trade secrets, patent applications in preparation,
193pricing information, subcontractor information, client data, personnel
194data, financial information, etc. Currently, anyone with access to
195the network (any machine on the network) can listen to anything that
196goes in the network, without any regard to normal access restrictions.
197
198
199<p>
200Many companies are not aware that information can so easily be
201recovered from the network. They trust that their data is safe
202since nobody is supposed to know that there is sensitive information
203in the network, or because so much other data is transferred in the
204network. This is not a safe policy.
205
206
207<h2><a name= "1.3">1.3 - What operating systems are supported?</a></h2>
208
209<p>
210Even though OpenSSH is developed on
211<a href="http://www.openbsd.org/">OpenBSD</a> a wide variety of
212ports to other operating systems exist. The portable version of OpenSSH
213is headed by <a href="mailto:djm@openbsd.org">Damien Miller</a>.
214For a quick overview of the portable version of OpenSSH see
215<a href="http://www.openssh.com/portable.html">OpenSSH Portable Release</a>.
216Currently, the supported operating systems are:
217
218
219<ul>
220 <li>OpenBSD
221 <li>NetBSD
222 <li>FreeBSD
223 <li>AIX
224 <li>HP-UX
225 <li>IRIX
226 <li>Linux
227 <li>NeXT
228 <li>SCO
229 <li>SNI/Reliant Unix
230 <li>Solaris
231 <li>Digital Unix/Tru64/OSF
232 <li>Mac OS X
233 <li>Cygwin
234</ul>
235
236<p>
237A list of vendors that include OpenSSH in their distributions
238is located in the <a href="http://www.openssh.com/users.html">OpenSSH Users page</a>.
239
240<h2><a name= "1.4">1.4 - What about copyrights, usage and patents?</a></h2>
241<p>
242The OpenSSH developers have tried very hard to keep OpenSSH free of any
243patent or copyright problems. To do this, some options had to be
244stripped from OpenSSH. Namely support for patented algorithms.
245
246<p>
247OpenSSH does not support any patented transport algorithms. In SSH1 mode,
248only 3DES and Blowfish are available options. In SSH2 mode, only 3DES,
249Blowfish, CAST128, Arcfour and AES can be selected.
250The patented IDEA algorithm is not supported.
251
252<p>
253OpenSSH provides support for both SSH1 and SSH2 protocols.
254
255<p>
256Since the RSA patent has expired, there are no restrictions on the use
257of RSA algorithm using software, including OpenBSD.
258
259<h2><a name= "1.5">1.5 - Where should I ask for help?</a></h2>
260<p>
261There are many places to turn to for help. In addition to the main
262<a href="http://www.openssh.com/index.html">OpenSSH website</a>,
263there are many mailing lists to try. Before trying any mailing lists,

282
283<h2><a name= "2.1">2.1 - Why does ssh/scp make connections from low-numbered ports.</a></h2>
284<p>
285The OpenSSH client uses low numbered ports for rhosts and rhosts-rsa
286authentication because the server needs to trust the username provided by
287the client. To get around this, you can add the below example to your
288<i>ssh_config</i> or <i>~/.ssh/config</i> file.
289
290
291<blockquote>
292<table border=0 width="800">

315
316<h2><a name= "2.2">2.2 - Why is the ssh client setuid root?</a></h2>
317
318<p>
319In conjunction with the previous question, (<a href="#2.1">2.1</a>)
320OpenSSH needs root authority to be able to bind to low-numbered ports to
321facilitate <i>rhosts authentication</i>.
322A privileged port is also required for rhosts-rsa authentication to older
323SSH releases.
324
325<p>
326Additionally, for both <i>rhosts-rsa authentication</i> (in protocol
327version 1) and <i>hostbased authentication</i> (in protocol version 2)
328the ssh client needs to access the <i>private host key</i> in order to
329authenticate the client machine to the server.
330OpenSSH versions prior to 3.3 required the <code>ssh</code> binary to be
331setuid root to enable this, and you may safely remove it if you don't
332want to use these authentication methods.
333
334<p>
335Starting in OpenSSH 3.3, <code>ssh</code> is not setuid by default. <a
336href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keysign">ssh-keysign</a>,
337is used for access to the private hosts keys, and ssh does not use privileged
338source ports by default. If you wish to use a privileged source port, you must
339manually set the setuid bit on <code>ssh</code>.
340
341<h2><a name= "2.3">2.3 - Why does SSH 2.3 have problems interoperating with OpenSSH 2.1.1?</a></h2>
342
343<p>
344SSH 2.3 and earlier versions contain a flaw in their HMAC implementation.
345Their code was not supplying the full data block output from the digest,
346and instead always provided 128 bits. For longer digests, this caused
347SSH 2.3 to not interoperate with OpenSSH.
348
349<p>
350OpenSSH 2.2.0 detects that SSH 2.3 has this flaw. Recent versions of SSH
351will have this bug fixed. Or you can add the following to
352SSH 2.3 <i>sshd2_config</i>.

365<h2><a name= "2.4">2.4 - Why does OpenSSH print: Dispatch protocol error: type 20</a></h2>
366
367<p>
368Problems in interoperation have been seen because older versions of
369OpenSSH did not support session rekeying. However the commercial SSH 2.3
370tries to negotiate this feature, and you might experience connection
371freezes or see the error message &quot;<b>Dispatch protocol error:
372type 20 </b>&quot;.
373To solve this problem, either upgrade to a recent OpenSSH release or
374disable rekeying by adding the following to your commercial SSH 2.3's
375<i>ssh2_config</i> or <i>sshd2_config</i>.
376
377
378<blockquote>

415Commercial SSH's
416<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keygen&amp;sektion=1">ssh-keygen(1)</a>
417program contained a bug which caused it to occasionally generate Pubkey
418Authentication (RSA or DSA) keys which had their Most Significant Bit
419(MSB) unset. Such keys were advertised as being full-length, but are
420actually, half the time, smaller than advertised.
421
422<p>
423OpenSSH will print warning messages when it encounters such keys. To rid
424yourself of these message, edit your <i>known_hosts</i> files and replace the
425incorrect key length (usually "1024") with the correct key length
426(usually "1023").

428<h2><a name= "2.7">2.7 - X11 and/or agent forwarding does not work.</a></h2>
429
430<p>
431Check your <i>ssh_config</i> and <i>sshd_config</i>. The default
432configuration files disable authentication agent and X11 forwarding. To
433enable it, put the line below in <i>sshd_config</i>:
434
435<blockquote>

458
459<p>

462>xauth(1)</a> binary. On OpenBSD this is in the <i>xbase</i> file
463set but will probably be different on other platforms. For OpenSSH
464Portable, xauth must be either found at configure time or specified
465via <b>XAuthLocation</b> in sshd_config(5) and ssh_config(5).
466
467<p>
468Note on agent interoperability: There are two different and
469incompatible agent forwarding mechanisms within the SSH2 protocol.
470OpenSSH has always used an extension of the original SSH1 agent
471requests, however some commercial products use a different, non-free
472agent forwarding protocol. This means that agent forwarding cannot
473be used between OpenSSH and those products.
474

513<h2><a name= "2.9">2.9 - sftp/scp fails at connection, but ssh is OK.</a></h2>
514
515<p>
516sftp and/or scp may fail at connection time if you have shell
517initialization (.profile, .bashrc, .cshrc, etc) which produces output
518for non-interactive sessions. This output confuses the sftp/scp client.
519You can verify if your shell is doing this by executing:
520
521<blockquote>
522<table border=0 width="800">
523 <tr>
524 <td nowrap bgcolor="#EEEEEE">
525<b>ssh yourhost /usr/bin/true</b>
526 </td>
527 </tr>
528</table>
529</blockquote>
530
531<p>
532If the above command produces any output, then you need to modify your
533shell initialization.
534
535<h2><a name= "2.10">2.10 - Will you add [foo] to scp?</a></h2>
536
537<p>
538Short Answer: no.
539
540<p>
541Long Answer: scp is not standardized. The closest thing it has to a
542specification is "what rcp does". Since the same command is used on both ends
543of the connection, adding features or options risks breaking interoperability with other
544implementations.
545
546<p>
547New features are more likely in sftp, since the protocol is standardized
548(well, a <a href="http://www.ietf.org/html.charters/OLD/secsh-charter.html">
549draft standard</a>), extensible, and the client and server are decoupled.
550
551<h2><a name= "2.11">2.11 - How do I use port forwarding?</a></h2>
552
553<p>
554If the remote server is running sshd(8), it may be possible to
555``tunnel'' certain services via ssh. This may be desirable, for
556example, to encrypt POP or SMTP connections, even though the software
557does not directly support encrypted communications. Tunnelling uses
558port forwarding to create a connection between the client and server.
559The client software must be able to specify a non-standard port to
560connect to for this to work.
561
562<p>
563The idea is that the user connects to the remote host using ssh,
564and specifies which port on the client's machine should be used to
565forward connections to the remote server. After that it is possible
566to start the service which is to be encrypted (e.g. fetchmail, irc)
567on the client machine, specifying the same local port passed to
568ssh, and the connection will be tunnelled through ssh. By default,
569the system running the forward will only accept connections from
570itself.
571
572<p>
573The options most relevant to tunnelling are the -L and -R options,
574which allow the user to forward connections, the -D option, which
575permits dynamic port forwarding, the -g option, which permits other
576hosts to use port forwards, and the -f option, which instructs ssh
577to put itself in the background after authentication. See the <a
578href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1"
579>ssh(1)</a> man page for further details.
580
581<p>
582This is an example of tunnelling an IRC session from client machine
583``127.0.0.1'' (localhost) to remote server ``server.example.com'':
584
585<blockquote>
586<table border=0 width="800">
587 <tr>
588 <td nowrap bgcolor="#EEEEEE">
589<b>ssh -f -L 1234:server.example.com:6667 server.example.com sleep 10<br>
590irc -c '#users' -p 1234 pinky 127.0.0.1</b>
591 </td>
592 </tr>
593</table>
594</blockquote>
595
596<p>
597This tunnels a connection to IRC server server.example.com, joining
598channel ``#users'', using the nickname ``pinky''. The local port used
599in this example is 1234. It does not matter which port is used, as
600long as it's greater than 1023 (remember, only root can open sockets on
601privileged ports) and doesn't conflict with any ports already in use.
602The connection is forwarded to port 6667 on the remote server, since
603that's the standard port for IRC services.
604
605<p>
606The remote command ``sleep 10'' was specified to allow an amount
607of time (10 seconds, in the example) to start the service which is to
608be tunnelled. If no connections are made within the time specified,
609ssh will exit. If more time is required, the sleep(1) value can be
610increased appropriately or, alternatively, the example above could
611be added as a function to the user's shell. See ksh(1) and csh(1)
612for more details about user-defined functions.
613
614<p>
615ssh also has an -N option, convenient for use with port forwarding:
616if -N is specified, it is not necessary to specify a remote command
617(``sleep 10'' in the example above). However, use of this option
618causes ssh to wait around for ever (as opposed to exiting after a
619remote command has completed), and the user must take care to manually
620kill(1) the process afterwards.
621
622<h2><a name= "2.12">2.12 - My ssh connection freezes or drops out after N minutes of inactivity.</a></h2>
623
624<p>
625This is usually the result of a packet filter or NAT device
626timing out your TCP connection due to inactivity. You can enable
627<b>ClientAliveInterval</b> in the server's <i><a
628href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&amp;sektion=5">
629sshd_config</a></i>, or enable <b>ServerAliveInterval</b> in the
630client's <i><a
631href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh_config&amp;sektion=5">
632ssh_config</a></i> (the latter is available in OpenSSH 3.8 and newer).
633
634<p>
635Enabling either option and setting the interval for less than the time
636it takes to time out your session will ensure that the connection is
637kept "fresh" in the device's connection table.

669This information is used by clients and servers to enable protocol

679
680<p>
681The portable version of OpenSSH will generate spurious authentication

690 </td>
691 </tr>
692</table>
693</blockquote>
694
695<p>
696These are generated because OpenSSH first tries to determine whether a
697user needs authentication to login (e.g. empty password). Unfortunately
698PAM likes to log all authentication events, this one included.
699
700<p>
701If it annoys you too much, set &quot;<b>PermitEmptyPasswords no</b>&quot;
702in <i>sshd_config</i>. This will quiet the error message at the expense
703of disabling logins to accounts with no password set.
704This is the default if you use the supplied <i>sshd_config</i> file.
705
706<h2><a name= "3.2">3.2 - Empty passwords not allowed with PAM authentication.</a></h2>
707
708<p>
709To enable empty passwords with a version of OpenSSH built with PAM you
710must add the flag nullok to the end of the password checking module
711in the <i>/etc/pam.d/sshd</i> file. For example:
712
713<blockquote>
714<table border=0 width="800">
715 <tr>
716 <td nowrap bgcolor="#EEEEEE">
717auth required/lib/security/pam_unix.so shadow nodelay nullok
718 </td>
719 </tr>
720</table>
721</blockquote>
722
723<p>
724This must be done in addition to setting &quot;<b>PermitEmptyPasswords
725yes</b>&quot; in the <i>sshd_config</i> file.
726
727<p>
728There is one caveat when using empty passwords with PAM authentication:
729PAM will allow any password when authenticating an account with an empty
730password. This breaks the check that
731<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&amp;sektion=8">sshd(8)</a>
732uses to determine whether an account has no password set and grant
733users access to the account regardless of the policy specified by
734<b>PermitEmptyPasswords</b>. For this reason, it is recommended that you
735do not add the <b>nullok</b> directive to your PAM configuration file
736unless you specifically wish to allow empty passwords.

746<li>Some versions of glibc (notably glibc 2.1 shipped with Red Hat 6.1)
747can take a long time to resolve "IPv6 or IPv4" addresses from domain

749inet</b> option in <i>ssh_config</i>.</li>
750
751<li>There may be a DNS lookup problem, either at the client or server.
752You can use the <code>nslookup</code> command to check this on both client
753and server by looking up the other end's name and IP address. In
754addition, on the server look up the name returned by the client's
755IP-name lookup. You can disable most of the server-side lookups by

760Delays less than 10 seconds can have other causes.

763
764<li>OpenSSH releases prior to 3.8 had an <i>moduli</i> file with
765moduli that were just smaller than what sshd would look for, and
766as a result, sshd would end up using moduli significantly larger
767than requested, which resulted in a speed penalty. Replacing the

769file will not be replaced during an upgrade and must be replaced
770manually).</li>
771
772<li>OpenSSH releases prior to 3.8 had a flaw in <code>ssh</code> that
773would cause it to request moduli larger than intended (which when
774combined with the above resulted in significant slowdowns).

781one of the programs called by <code>ssh-rand-helper</code> to

801<h3>How slow is "slow"?</h3>
802Under normal conditions, the speed of SSH logins is dependant on
803CPU speed of client and server. For comparison the following are
804typical connect times for <code>time ssh localhost true</code>

806OpenSSL were compiled with gcc 3.3.x.

833
834<p>
835The Linux kernel is looking (via modprobe) for protocol family 10 (IPv6).
836Either load the appropriate kernel module, enter the correct alias in
837<i>/etc/modules.conf</i> or disable IPv6 in <i>/etc/modules.conf</i>.
838
839
840<p>

842<i>/etc/conf.modules</i>.

845<h2><a name= "3.5">3.5 - Password authentication doesn't work (eg on Slackware 7.0 or Red Hat 6.x)</a></h2>
846
847<p>
848If the password is correct password the login is still denied, the
849usual cause is that the system is configured to use MD5-type passwords
850but the
851<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=crypt&amp;sektion=3"
852>crypt(3)</a> function used by sshd doesn't understand them.
853
854<p>
855Affected accounts will have password strings in <i>/etc/passwd</i>
856or <i>/etc/shadow</i> that start with <b>$1$</b>.
857If password authentication fails for new accounts or accounts with
858recently changed passwords, but works for old accounts, this is the
859likely culprit.
860
861<p>
862The underlying cause is that some versions of OpenSSL have a crypt(3)
863function that does not understand MD5 passwords, and the link order of
864sshd means that OpenSSL's crypt(3) is used instead of the system's.
865OpensSSH's configure attempts to correct for this but is not always
866successful.
867
868<p>
869There are several possible solutions:
870
871<ul>
872<li>
873<p>
874Enable sshd's built-in support for MD5 passwords at build time.
875
876<blockquote>

879 <td nowrap bgcolor="#EEEEEE">
880./configure --with-md5-passwords [options]
881 </td>
882 </tr>
883</table>
884</blockquote>
885
886This is safe even if you have both types of encryption as sshd will
887select the correct algorithm for each account automatically.
888
889<li>
890<p>
891If your system has a separate libcrypt library (eg Slackware 7) then you
892can manually add -lcrypt to the LIBS list so it's used instead of
893OpenSSL's:
894
895<blockquote>
896<table border=0 width="800">
897 <tr>
898 <td nowrap bgcolor="#EEEEEE">

900 </td>
901 </tr>
902</table>
903</blockquote>
904
905<li>
906<p>
907If your platforms supports PAM, you may configure sshd to use it
908(see <a href= "#3.15" >section 3.15</a>). This will mean that sshd will
909not verify passwords itself but will defer to the configured PAM modules.
910</ul>
911
912<h2><a name= "3.6">3.6 - Configure or sshd(8) complain about lack of RSA or DSA support</a></h2>

923must be in the default PATH on both the client and the server. You may
924need to use the <b>--with-default-path</b> option to specify a custom
925path to search on the server. This option replaces the default path,
926so you need to specify all the current directories on your path as well
927as where you have installed scp. For example:
928
929<blockquote>
930<table border=0 width="800">
931 <tr>

934 </td>
935 </tr>
936</table>
937</blockquote>
938
939<p>
940Note that configuration by the server's admin will take precedence over the
941setting of <b>--with-default-path</b>. This includes resetting PATH in
942<i>/etc/profile</i>, PATH in <i>/etc/environment</i> on AIX, or (for 3.7p1 and
943above) setting PATH or SUPATH in <i>/etc/default/login</i> on Solaris or
944Reliant Unix.
945
946<h2><a name= "3.8">3.8 - Unable to read passphrase</a></h2>
947
948<p>
949Some operating systems set <i>/dev/tty</i> with incorrect modes, causing
950the reading of passwords to fail with the following error:
951
952<blockquote>
953<table border=0 width="800">

957 </td>
958 </tr>
959</table>
960</blockquote>
961
962<p>
963The solution to this is to reset the permissions on <i>/dev/tty</i>
964to mode 0666 and report the error as a bug to your OS vendor.
965

970If there is no 'configure' file in the tar.gz file that you downloaded

972downloaded the OpenBSD distribution of OpenSSH and are attempting to
973compile it on another platform. Please refer to the information on the

978
979<p>
980OpenSSH may hang when exiting. This can occur when there is an active
981background process. This is known to occur on Linux and HP-UX.
982The problem can be verified by doing the following:
983
984<blockquote>
985<table border=0 width="800">
986 <tr>
987 <td nowrap bgcolor="#EEEEEE">
988$ <b>sleep 20 &amp; exit</b>

1000 </td>
1001 </tr>
1002</table>
1003</blockquote>
1004
1005<p>
1006A work around for bash users is to place <b>"shopt -s huponexit"</b>
1007in either /etc/bashrc or ~/.bashrc. Otherwise, consult your shell's
1008man page for an option to enable it to send a HUP signal to active
1009jobs when exiting. See <a

1046with this configuration.<p>
1047
1048In general, X11 clients using X11 R6 should work with the default
1049setting. Some vendors, including HP, ship X11 clients with R6
1050and R5 libs, so some clients will work, and others will not work.
1051This is true for HP-UX 11.X.<p>
1052
1053<h2><a name= "3.13">3.13 - I upgraded to OpenSSH 3.8 and some

1071
1072<p>
1073Typically this is caused by the file permissions on $HOME, $HOME/.ssh or
1074$HOME/.ssh/authorized_keys being more permissive than sshd allows by default.
1075
1076<p>
1077In this case, it can be solved by executing the following on the server.

1090<p>
1091If this is not possible for some reason, an alternative is to set

1110
1111To use PAM at all, this option must be provided at build time.
1112The run-time behaviour when PAM is built in varies with the version of
1113Portable OpenSSH, and on later versions it must also be enabled by setting
1114<b>UsePAM</b> to <b>yes</b> in <i>sshd_config</i>.
1115
1116<p>
1117The behaviour of the relevant authentications options when PAM support is built
1118in is summarised by the following table.

1156OpenSSH Portable's PAM interface still has problems with a few modules,
1157however we hope that this number will reduce in the future. As at the

1174
1175Between AIX 4.3.3 and AIX 5.x, the format of the wtmp struct changed. This
1176means that sshd binaries built on AIX 4.x will not correctly write wtmp
1177entries when run on AIX 5.x. This can be fixed by simply recompiling
1178sshd on an AIX 5.x system and using that.

1.TH GNOME-SSH-ASKPASS 1
2.SH NAME
3gnome\-ssh\-askpass \- prompts a user for a passphrase using GNOME
4.SH SYNOPSIS
5.B gnome\-ssh\-askpass
6.SH DESCRIPTION
7.B gnome\-ssh\-askpass
8is a GNOME-based passphrase dialog for use with OpenSSH.
9It is intended to be called by the
10.BR ssh\-add (1)
11program and not invoked directly.
12It allows
13.BR ssh\-add (1)
14to obtain a passphrase from a user, even if not connected to a terminal
15(assuming that an X display is available).
16This happens automatically in the case where
17.B ssh\-add
18is invoked from one's
19.B ~/.xsession
20or as one of the GNOME startup programs, for example.
21.PP
22In order to be called automatically by
23.BR ssh\-add ,
24.B gnome\-ssh\-askpass
25should be installed as
26.IR /usr/bin/ssh\-askpass .
27.SH "ENVIRONMENT VARIABLES"
28The following environment variables are recognized:
29.TP
30.I GNOME_SSH_ASKPASS_GRAB_SERVER
31Causes
32.B gnome\-ssh\-askpass
33to grab the X server before asking for a passphrase.
34.TP
35.I GNOME_SSH_ASKPASS_GRAB_POINTER
36Causes
37.B gnome\-ssh\-askpass
38to grab the mouse pointer using
39.IR gdk_pointer_grab ()
40before asking for a passphrase.
41.PP
42Regardless of whether either of these environment variables is set,
43.B gnome\-ssh\-askpass
44will grab the keyboard using
45.IR gdk_keyboard_grab ().
46.SH AUTHOR
47This manual page was written by Colin Watson <cjwatson@debian.org>
48for the Debian system (but may be used by others).
49It was based on that for

4_Description: Disable SSH password authentication for root?
5 Previous versions of openssh-server permitted logging in as root over SSH
6 using password authentication. The default for new installations is now
7 "PermitRootLogin prohibit-password", which disables password authentication
8 for root without breaking systems that have explicitly configured SSH
9 public key authentication for root.
10 .
11 This change makes systems more secure against brute-force password
12 dictionary attacks on the root user (a very common target for such
13 attacks). However, it may break systems that are set up with the
14 expectation of being able to SSH as root using password authentication. You
15 should only make this change if you do not need to do that.
16
17Template: openssh-server/password-authentication
18Type: boolean
19Default: true
20Description: Allow password authentication?
21 By default, the SSH server will allow authenticating using a password.
22 You may want to change this if all users on this system authenticate using
23 a stronger authentication method, such as public keys.

4Subject: upstream: check in scp client that filenames sent during
5
6remote->local directory copies satisfy the wildcard specified by the user.
7
8This checking provides some protection against a malicious server
9sending unexpected filenames, but it comes at a risk of rejecting wanted
10files due to differences between client and server wildcard expansion rules.
11
12For this reason, this also adds a new -T flag to disable the check.

4Subject: GSSAPI key exchange support
5
6This patch has been rejected upstream: "None of the OpenSSH developers are
7in favour of adding this, and this situation has not changed for several
8years. This is not a slight on Simon's patch, which is of fine quality, but
9just that a) we don't trust GSSAPI implementations that much and b) we don't
10like adding new KEX since they are pre-auth attack surface. This one is
11particularly scary, since it requires hooks out to typically root-owned
12system resources."
13
14However, quite a lot of people rely on this in Debian, and it's better to
15have it merged into the main openssh package rather than having separate
16-krb5 packages (as we used to have). It seems to have a generally good
17security history.

4Subject: Various keepalive extensions
5
6Add compatibility aliases for ProtocolKeepAlives and SetupTimeOut, supported
7in previous versions of Debian's OpenSSH package but since superseded by
8ServerAliveInterval. (We're probably stuck with this bit for
9compatibility.)
10
11In batch mode, default ServerAliveInterval to five minutes.
12
13Adjust documentation to match and to give some more advice on use of
14keepalives.

4Subject: Don't check the status field of the OpenSSL version
5
6There is no reason to check the version of OpenSSL (in Debian). If it's
7not compatible the soname will change. OpenSSH seems to want to do a
8check for the soname based on the version number, but wants to keep the
9status of the release the same. Remove that check on the status since
10it doesn't tell you anything about how compatible that version is.

4Subject: Include the Debian version in our identification
5
6This makes it easier to audit networks for versions patched against security
7vulnerabilities. It has little detrimental effect, as attackers will
8generally just try attacks rather than bothering to scan for
9vulnerable-looking version strings. (However, see debian-banner.patch.)

4Subject: Restore reading authorized_keys2 by default
5
6Upstream seems to intend to gradually phase this out, so don't assume
7that this will remain the default forever. However, we were late in
8adopting the upstream sshd_config changes, so it makes sense to extend
9the grace period.

4Subject: Restore TCP wrappers support
5
6Support for TCP wrappers was dropped in OpenSSH 6.7. See this message
7and thread:
8
9 https://lists.mindrot.org/pipermail/openssh-unix-dev/2014-April/032497.html
10
11It is true that this reduces preauth attack surface in sshd. On the
12other hand, this support seems to be quite widely used, and abruptly
13dropping it (from the perspective of users who don't read
14openssh-unix-dev) could easily cause more serious problems in practice.
15
16It's not entirely clear what the right long-term answer for Debian is,
17but it at least probably doesn't involve dropping this feature shortly
18before a freeze.

4Subject: Allow flock and ipc syscall for s390 architecture
5
6In order to use the OpenSSL-ibmpkcs11 engine it is needed to allow flock
7and ipc calls, because this engine calls OpenCryptoki (a PKCS#11
8implementation) which calls the libraries that will communicate with the
9crypto cards. OpenCryptoki makes use of flock and ipc and, as of now,
10this is only need on s390 architecture.

4Subject: Handle SELinux authorisation roles
5
6Rejected upstream due to discomfort with magic usernames; a better approach
7will need an SSH protocol change. In the meantime, this came from Debian's
8SELinux maintainer, so we'll keep it until we have something better.

4Subject: ssh(1): Refer to ssh-argv0(1)
5
6Old versions of OpenSSH (up to 2.5 or thereabouts) allowed creating symlinks
7to ssh with the name of the host you want to connect to. Debian ships an
8ssh-argv0 script restoring this feature; this patch refers to its manual
9page from ssh(1).

4Subject: Accept obsolete ssh-vulnkey configuration options
5
6These options were used as part of Debian's response to CVE-2008-0166.
7Nearly six years later, we no longer need to continue carrying the bulk
8of that patch, but we do need to avoid failing when the associated
9configuration options are still present.

4Subject: "LogLevel SILENT" compatibility
5
6"LogLevel SILENT" (-qq) was introduced in Debian openssh 1:3.0.1p1-1 to
7match the behaviour of non-free SSH, in which -q does not suppress fatal
8errors. However, this was unintentionally broken in 1:4.6p1-2 and nobody
9complained, so we've dropped most of it. The parts that remain are basic
10configuration file compatibility, and an adjustment to "Pseudo-terminal will
11not be allocated ..." which should be split out into a separate patch.

4Subject: Allow harmless group-writability
5
6Allow secure files (~/.ssh/config, ~/.ssh/authorized_keys, etc.) to be
7group-writable, provided that the group in question contains only the file's
8owner. Rejected upstream for IMO incorrect reasons (e.g. a misunderstanding
9about the contents of gr->gr_mem). Given that per-user groups and umask 002
10are the default setup in Debian (for good reasons - this makes operating in
11setgid directories with other groups much easier), we need to permit this by
12default.

41.Sh DESCRIPTION
42.Nm
43replaces the old ssh command-name as hostname handling.
44If you link to this script with a hostname then executing the link is
45equivalent to having executed ssh with that hostname as an argument.
46All other arguments are passed to ssh and will be processed normally.
47.Sh OPTIONS
48See
49.Xr ssh 1 .
50.Sh FILES
51See
52.Xr ssh 1 .
53.Sh AUTHORS
