- Fix IPQoS not being set on non-mapped v4-in-v6 addressed connections
(closes: #643312, #650512).
- Add a new privilege separation sandbox implementation for Linux's new
seccomp sandbox, automatically enabled on platforms that support it.
(Note: privilege separation sandboxing is still experimental.)

memleak in key_load_file(); from Jan Klemkow
|

- 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).

- 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).

[authfile.c key.c key.h ssh-keygen.c]
fix a possible NULL deref on loading a corrupt ECDH key
store ECDH group information in private keys files as "named groups"
rather than as a set of explicit group parameters (by setting
the OPENSSL_EC_NAMED_CURVE flag). This makes for shorter key files and
retrieves the group's OpenSSL NID that we need for various things.

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.
Only the mandatory sections of RFC5656 are implemented, specifically the
three REQUIRED curves nistp256, nistp384 and nistp521 and only ECDH and
ECDSA. Point compression (optional in RFC5656 is NOT implemented).
Certificate host and user keys using the new ECDSA key types are supported.
Note that this code has not been tested for interoperability and may be
subject to change.

- 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).

- 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).

- Add key blacklisting support. Keys listed in
/etc/ssh/blacklist.TYPE-LENGTH will be rejected for authentication by
sshd, unless "PermitBlacklistedKeys yes" is set in
/etc/ssh/sshd_config.
- Add a new program, ssh-vulnkey, which can be used to check keys
against these blacklists.
- Depend on openssh-blacklist.
- Force dependencies on libssl0.9.8 / libcrypto0.9.8-udeb to at least
0.9.8g-9.
- Automatically regenerate known-compromised host keys, with a
critical-priority debconf note. (I regret that there was no time to
gather translations.)
