* 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;
