2011-09-06* New upstream release (http://www.openssh.org/txt/release-5.9).Colin Watson
- Introduce sandboxing of the pre-auth privsep child using an optional sshd_config(5) "UsePrivilegeSeparation=sandbox" mode that enables mandatory restrictions on the syscalls the privsep child can perform. - Add new SHA256-based HMAC transport integrity modes from http://www.ietf.org/id/draft-dbider-sha2-mac-for-ssh-02.txt. - The pre-authentication sshd(8) privilege separation slave process now logs via a socket shared with the master process, avoiding the need to maintain /dev/log inside the chroot (closes: #75043, #429243, #599240). - ssh(1) now warns when a server refuses X11 forwarding (closes: #504757). - sshd_config(5)'s AuthorizedKeysFile now accepts multiple paths, separated by whitespace (closes: #76312). The authorized_keys2 fallback is deprecated but documented (closes: #560156). - ssh(1) and sshd(8): set IPv6 traffic class from IPQoS, as well as IPv4 ToS/DSCP (closes: #498297). - ssh-add(1) now accepts keys piped from standard input. E.g. "ssh-add - < /path/to/key" (closes: #229124). - Clean up lost-passphrase text in ssh-keygen(1) (closes: #444691). - Say "required" rather than "recommended" in unprotected-private-key warning (LP: #663455).

[sshconnect.c] remove extra newline
2011-01-24* New upstream release (http://www.openssh.org/txt/release-5.7):Colin Watson
- Implement Elliptic Curve Cryptography modes for key exchange (ECDH) and host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA offer better performance than plain DH and DSA at the same equivalent symmetric key length, as well as much shorter keys. - sftp(1)/sftp-server(8): add a protocol extension to support a hard link operation. It is available through the "ln" command in the client. The old "ln" behaviour of creating a symlink is available using its "-s" option or through the preexisting "symlink" command. - scp(1): Add a new -3 option to scp: Copies between two remote hosts are transferred through the local host (closes: #508613). - ssh(1): "atomically" create the listening mux socket by binding it on a temporary name and then linking it into position after listen() has succeeded. This allows the mux clients to determine that the server socket is either ready or stale without races (closes: #454784). Stale server sockets are now automatically removed (closes: #523250). - ssh(1): install a SIGCHLD handler to reap expired child process (closes: #594687). - ssh(1)/ssh-agent(1): honour $TMPDIR for client xauth and ssh-agent temporary directories (closes: #357469, although only if you arrange for ssh-agent to actually see $TMPDIR since the setgid bit will cause it to be stripped off).

- Added a ControlPersist option to ssh_config(5) that automatically starts a background ssh(1) multiplex master when connecting. This connection can stay alive indefinitely, or can be set to automatically close after a user-specified duration of inactivity (closes: #335697, #350898, #454787, #500573, #550262). - Support AuthorizedKeysFile, AuthorizedPrincipalsFile, HostbasedUsesNameFromPacketOnly, and PermitTunnel in sshd_config(5) Match blocks (closes: #549858). - sftp(1): fix ls in working directories that contain globbing characters in their pathnames (LP: #530714).

[sshconnect.c] fix terminology: we didn't find a certificate in known_hosts, we found a CA key
2010-03-31* New upstream release (LP: #535029).Colin Watson
- After a transition period of about 10 years, this release disables SSH protocol 1 by default. Clients and servers that need to use the legacy protocol must explicitly enable it in ssh_config / sshd_config or on the command-line. - Remove the libsectok/OpenSC-based smartcard code and add support for PKCS#11 tokens. This support is enabled by default in the Debian packaging, since it now doesn't involve additional library dependencies (closes: #231472, LP: #16918). - Add support for certificate authentication of users and hosts using a new, minimal OpenSSH certificate format (closes: #482806). - Added a 'netcat mode' to ssh(1): "ssh -W host:port ...". - Add the ability to revoke keys in sshd(8) and ssh(1). (For the Debian package, this overlaps with the key blacklisting facility added in openssh 1:4.7p1-9, but with different file formats and slightly different scopes; for the moment, I've roughly merged the two.) - Various multiplexing improvements, including support for requesting port-forwardings via the multiplex protocol (closes: #360151). - Allow setting an explicit umask on the sftp-server(8) commandline to override whatever default the user has (closes: #496843). - Many sftp client improvements, including tab-completion, more options, and recursive transfer support for get/put (LP: #33378). The old mget/mput commands never worked properly and have been removed (closes: #270399, #428082). - Do not prompt for a passphrase if we fail to open a keyfile, and log the reason why the open failed to debug (closes: #431538). - Prevent sftp from crashing when given a "-" without a command. Also, allow whitespace to follow a "-" (closes: #531561).

OpenSSH certificate key types are not X.509 certificates, but a much simpler format that encodes a public key, identity information and some validity constraints and signs it with a CA key. CA keys are regular SSH keys. This certificate style avoids the attack surface of X.509 certificates and is very easy to deploy. Certified host keys allow automatic acceptance of new host keys when a CA certificate is marked as sh/known_hosts. see VERIFYING HOST KEYS in ssh(1) for details. Certified user keys allow authentication of users when the signing CA key is marked as trusted in authorized_keys. See "AUTHORIZED_KEYS FILE FORMAT" in sshd(8) for details. Certificates are minted using ssh-keygen(1), documentation is in the "CERTIFICATES" section of that manpage.

2010-01-01* New upstream release (closes: #536182). Yes, I know 5.3p1 has been outColin Watson
for a while, but there's no GSSAPI patch available for it yet. - Change the default cipher order to prefer the AES CTR modes and the revised "arcfour256" mode to CBC mode ciphers that are susceptible to CPNI-957037 "Plaintext Recovery Attack Against SSH". - Add countermeasures to mitigate CPNI-957037-style attacks against the SSH protocol's use of CBC-mode ciphers. Upon detection of an invalid packet length or Message Authentication Code, ssh/sshd will continue reading up to the maximum supported packet length rather than immediately terminating the connection. This eliminates most of the known differences in behaviour that leaked information about the plaintext of injected data which formed the basis of this attack (closes: #506115, LP: #379329). - ForceCommand directive now accepts commandline arguments for the internal-sftp server (closes: #524423, LP: #362511). - Add AllowAgentForwarding to available Match keywords list (closes: #540623). - Make ssh(1) send the correct channel number for SSH2_MSG_CHANNEL_SUCCESS and SSH2_MSG_CHANNEL_FAILURE messages to avoid triggering 'Non-public channel' error messages on sshd(8) in openssh-5.1. - Avoid printing 'Non-public channel' warnings in sshd(8), since the ssh(1) has sent incorrect channel numbers since ~2004 (this reverts a behaviour introduced in openssh-5.1; closes: #496017). * Update to GSSAPI patch from http://www.sxw.org.uk/computing/patches/openssh-5.2p1-gsskex-all-20090726.patch, including cascading credentials support (LP: #416958).

backported to 4.7p1: - 4.9/4.9p1 (http://www.openssh.com/txt/release-4.9): + Added chroot(2) support for sshd(8), controlled by a new option "ChrootDirectory" (closes: #139047, LP: #24777). + Linked sftp-server(8) into sshd(8). The internal sftp server is used when the command "internal-sftp" is specified in a Subsystem or ForceCommand declaration. When used with ChrootDirectory, the internal sftp server requires no special configuration of files inside the chroot environment. + Added a protocol extension method "posix-rename@openssh.com" for sftp-server(8) to perform POSIX atomic rename() operations; sftp(1) prefers this if available (closes: #308561). + Removed the fixed limit of 100 file handles in sftp-server(8). + ssh(8) will now skip generation of SSH protocol 1 ephemeral server keys when in inetd mode and protocol 2 connections are negotiated. This speeds up protocol 2 connections to inetd-mode servers that also allow Protocol 1. + Accept the PermitRootLogin directive in a sshd_config(5) Match block. Allows for, e.g. permitting root only from the local network. + Reworked sftp(1) argument splitting and escaping to be more internally consistent (i.e. between sftp commands) and more consistent with sh(1). Please note that this will change the interpretation of some quoted strings, especially those with embedded backslash escape sequences. + Support "Banner=none" in sshd_config(5) to disable sending of a pre-login banner (e.g. in a Match block). + ssh(1) ProxyCommands are now executed with $SHELL rather than /bin/sh. + ssh(1)'s ConnectTimeout option is now applied to both the TCP connection and the SSH banner exchange (previously it just covered the TCP connection). This allows callers of ssh(1) to better detect and deal with stuck servers that accept a TCP connection but don't progress the protocol, and also makes ConnectTimeout useful for connections via a ProxyCommand. + scp(1) incorrectly reported "stalled" on slow copies (closes: #140828). + scp(1) date underflow for timestamps before epoch. + ssh(1) used the obsolete SIG DNS RRtype for host keys in DNS, instead of the current standard RRSIG. + Correctly drain ACKs when a sftp(1) upload write fails midway, avoids a fatal() exit from what should be a recoverable condition. + Fixed ssh-keygen(1) selective host key hashing (i.e. "ssh-keygen -HF hostname") to not include any IP address in the data to be hashed. + Make ssh(1) skip listening on the IPv6 wildcard address when a binding address of 0.0.0.0 is used against an old SSH server that does not support the RFC4254 syntax for wildcard bind addresses. + Enable IPV6_V6ONLY socket option on sshd(8) listen socket, as is already done for X11/TCP forwarding sockets (closes: #439661). + Fix FD leak that could hang a ssh(1) connection multiplexing master. + Make ssh(1) -q option documentation consistent with reality. + Fixed sshd(8) PAM support not calling pam_session_close(), or failing to call it with root privileges (closes: #372680). + Fix activation of OpenSSL engine support when requested in configure (LP: #119295). - 5.1/5.1p1 (http://www.openssh.com/txt/release-5.1): + Introduce experimental SSH Fingerprint ASCII Visualisation to ssh(1) and ssh-keygen(1). Visual fingerprint display is controlled by a new ssh_config(5) option "VisualHostKey". The intent is to render SSH host keys in a visual form that is amenable to easy recall and rejection of changed host keys. + sshd_config(5) now supports CIDR address/masklen matching in "Match address" blocks, with a fallback to classic wildcard matching. + sshd(8) now supports CIDR matching in ~/.ssh/authorized_keys from="..." restrictions, also with a fallback to classic wildcard matching. + Added an extended test mode (-T) to sshd(8) to request that it write its effective configuration to stdout and exit. Extended test mode also supports the specification of connection parameters (username, source address and hostname) to test the application of sshd_config(5) Match rules. + ssh(1) now prints the number of bytes transferred and the overall connection throughput for SSH protocol 2 sessions when in verbose mode (previously these statistics were displayed for protocol 1 connections only). + sftp-server(8) now supports extension methods statvfs@openssh.com and fstatvfs@openssh.com that implement statvfs(2)-like operations. + sftp(1) now has a "df" command to the sftp client that uses the statvfs@openssh.com to produce a df(1)-like display of filesystem space and inode utilisation (requires statvfs@openssh.com support on the server). + Added a MaxSessions option to sshd_config(5) to allow control of the number of multiplexed sessions supported over a single TCP connection. This allows increasing the number of allowed sessions above the previous default of 10, disabling connection multiplexing (MaxSessions=1) or disallowing login/shell/subsystem sessions entirely (MaxSessions=0). + Added a no-more-sessions@openssh.com global request extension that is sent from ssh(1) to sshd(8) when the client knows that it will never request another session (i.e. when session multiplexing is disabled). This allows a server to disallow further session requests and terminate the session in cases where the client has been hijacked. + ssh-keygen(1) now supports the use of the -l option in combination with -F to search for a host in ~/.ssh/known_hosts and display its fingerprint. + ssh-keyscan(1) now defaults to "rsa" (protocol 2) keys, instead of "rsa1". + Added an AllowAgentForwarding option to sshd_config(8) to control whether authentication agent forwarding is permitted. Note that this is a loose control, as a client may install their own unofficial forwarder. + ssh(1) and sshd(8): avoid unnecessary malloc/copy/free when receiving network data, resulting in a ~10% speedup. + ssh(1) and sshd(8) will now try additional addresses when connecting to a port forward destination whose DNS name resolves to more than one address. The previous behaviour was to try the only first address and give up if that failed. + ssh(1) and sshd(8) now support signalling that channels are half-closed for writing, through a channel protocol extension notification "eow@openssh.com". This allows propagation of closed file descriptors, so that commands such as "ssh -2 localhost od /bin/ls | true" do not send unnecessary data over the wire. + sshd(8): increased the default size of ssh protocol 1 ephemeral keys from 768 to 1024 bits. + When ssh(1) has been requested to fork after authentication ("ssh -f") with ExitOnForwardFailure enabled, delay the fork until after replies for any -R forwards have been seen. Allows for robust detection of -R forward failure when using -f. + "Match group" blocks in sshd_config(5) now support negation of groups. E.g. "Match group staff,!guests". + sftp(1) and sftp-server(8) now allow chmod-like operations to set set[ug]id/sticky bits. + The MaxAuthTries option is now permitted in sshd_config(5) match blocks. + Multiplexed ssh(1) sessions now support a subset of the ~ escapes that are available to a primary connection. + ssh(1) connection multiplexing will now fall back to creating a new connection in most error cases (closes: #352830). + Make ssh(1) deal more gracefully with channel requests that fail. Previously it would optimistically assume that requests would always succeed, which could cause hangs if they did not (e.g. when the server runs out of file descriptors). + ssh(1) now reports multiplexing errors via the multiplex slave's stderr where possible (subject to LogLevel in the mux master). + Prevent sshd(8) from erroneously applying public key restrictions leaned from ~/.ssh/authorized_keys to other authentication methods when public key authentication subsequently fails (LP: #161047). + Fixed an UMAC alignment problem that manifested on Itanium platforms.

While there, fix the behaviour that ssh would draw a random art picture on every newly seen host even when the option was not enabled. prodded by deraadt@, discussions, help and ok markus@ djm@ dtucker@

[dns.c canohost.c sshconnect.c] Do not pass "0" strings as ports to getaddrinfo because the lookups can slow things down and we never use the service info anyway. bz #859, patch from YOSHIFUJI Hideaki and John Devitofranceschi. ok deraadt@ djm@ djm belives that the reason for the "0" strings is to ensure that it's not possible to call getaddrinfo with both host and port being NULL. In the case of canohost.c host is a local array. In the case of sshconnect.c, it's checked for null immediately before use. In dns.c it ultimately comes from ssh.c:main() and is guaranteed to be non-null but it's not obvious, so I added a warning message in case it is ever passed a null.

[ssh_config.5 key.h readconf.c readconf.h ssh-keygen.1 ssh-keygen.c key.c sshconnect.c] Introduce SSH Fingerprint ASCII Visualization, a technique inspired by the graphical hash visualization schemes known as "random art", and by Dan Kaminsky's musings on the subject during a BlackOp talk at the 23C3 in Berlin. Scientific publication (original paper): "Hash Visualization: a New Technique to improve Real-World Security", Perrig A. and Song D., 1999, International Workshop on Cryptographic Techniques and E-Commerce (CrypTEC '99) http://sparrow.ece.cmu.edu/~adrian/projects/validation/validation.pdf The algorithm used here is a worm crawling over a discrete plane, leaving a trace (augmenting the field) everywhere it goes. Movement is taken from dgst_raw 2bit-wise. Bumping into walls makes the respective movement vector be ignored for this turn, thus switching to the other color of the chessboard. Graphs are not unambiguous for now, because circles in graphs can be walked in either direction. discussions with several people, help, corrections and ok markus@ djm@

[ssh.c sshconnect.c sshconnect.h] make ssh(1)'s ConnectTimeout option apply to both the TCP connection and SSH banner exchange (previously it just covered the TCP connection). This allows callers of ssh(1) to better detect and deal with stuck servers that accept a TCP connection but don't progress the protocol, and also makes ConnectTimeout useful for connections via a ProxyCommand; feedback and "looks ok" markus@
