* New upstream release (closes: #395507, #397961, #420035). Important
changes not previously backported to 4.3p2:
- 4.4/4.4p1 (http://www.openssh.org/txt/release-4.4):
+ On portable OpenSSH, fix a GSSAPI authentication abort that could be
used to determine the validity of usernames on some platforms.
+ Implemented conditional configuration in sshd_config(5) using the
"Match" directive. This allows some configuration options to be
selectively overridden if specific criteria (based on user, group,
hostname and/or address) are met. So far a useful subset of
post-authentication options are supported and more are expected to
be added in future releases.
+ Add support for Diffie-Hellman group exchange key agreement with a
final hash of SHA256.
+ Added a "ForceCommand" directive to sshd_config(5). Similar to the
command="..." option accepted in ~/.ssh/authorized_keys, this forces
the execution of the specified command regardless of what the user
requested. This is very useful in conjunction with the new "Match"
option.
+ Add a "PermitOpen" directive to sshd_config(5). This mirrors the
permitopen="..." authorized_keys option, allowing fine-grained
control over the port-forwardings that a user is allowed to
establish.
+ Add optional logging of transactions to sftp-server(8).
+ ssh(1) will now record port numbers for hosts stored in
~/.ssh/known_hosts when a non-standard port has been requested
(closes: #50612).
+ Add an "ExitOnForwardFailure" option to cause ssh(1) to exit (with a
non-zero exit code) when requested port forwardings could not be
established.
+ Extend sshd_config(5) "SubSystem" declarations to allow the
specification of command-line arguments.
+ Replacement of all integer overflow susceptible invocations of
malloc(3) and realloc(3) with overflow-checking equivalents.
+ Many manpage fixes and improvements.
+ Add optional support for OpenSSL hardware accelerators (engines),
enabled using the --with-ssl-engine configure option.
+ Tokens in configuration files may be double-quoted in order to
contain spaces (closes: #319639).
+ Move a debug() call out of a SIGCHLD handler, fixing a hang when the
session exits very quickly (closes: #307890).
+ Fix some incorrect buffer allocation calculations (closes: #410599).
+ ssh-add doesn't ask for a passphrase if key file permissions are too
liberal (closes: #103677).
+ Likewise, ssh doesn't ask either (closes: #99675).
- 4.6/4.6p1 (http://www.openssh.org/txt/release-4.6):
+ sshd now allows the enabling and disabling of authentication methods
on a per user, group, host and network basis via the Match directive
in sshd_config.
+ Fixed an inconsistent check for a terminal when displaying scp
progress meter (closes: #257524).
+ Fix "hang on exit" when background processes are running at the time
of exit on a ttyful/login session (closes: #88337).
* Update to current GSSAPI patch from
http://www.sxw.org.uk/computing/patches/openssh-4.6p1-gsskex-20070312.patch;
