[Bug 416958] Re: GSSAPI Cascading Credentials support

[Launchpad Bug Tracker]

This bug was fixed in the package openssh - 1:5.2p1-1ubuntu1

---------------
openssh (1:5.2p1-1ubuntu1) lucid; urgency=low

  * Resynchronise with Debian. Remaining changes:
    - Add support for registering ConsoleKit sessions on login.
    - Drop openssh-blacklist and openssh-blacklist-extra to Suggests; they
      take up a lot of CD space, and I suspect that rolling them out in
      security updates has covered most affected systems now.
  * Convert to Upstart. The init script is still here for the benefit of
    people running sshd in chroots. Note that the Upstart job does not
    support /etc/default/ssh, because it's much more straightforward to edit
    the job (/etc/init/ssh.conf) than it was to edit the init script.

openssh (1:5.2p1-1) unstable; urgency=low

  * New upstream release (closes: #536182). Yes, I know 5.3p1 has been out
    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).
    - Disable nonfunctional ssh(1) ~C escape handler in multiplex slave
      connections (closes: #507541).
    - Fix "whitepsace" typo in ssh_config(5) (closes: #514313, LP: #303835).
  * 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).
  * Use x11.pc when compiling/linking gnome-ssh-askpass2 (closes: #555951).
  * Moved to bzr.debian.org; add Vcs-Bzr and Vcs-Browser control fields.
  * Add debian/README.source with instructions on bzr handling.
  * Make ChrootDirectory work with SELinux (thanks, Russell Coker; closes:
    #556644).
  * Initialise sc to NULL in ssh_selinux_getctxbyname (thanks, Václav Ovsík;
    closes: #498684).
  * Don't duplicate backslashes when displaying server banner (thanks,
    Michał Górny; closes: #505378, LP: #425346).
  * Use hardening-includes for hardening logic (thanks, Kees Cook; closes:
    #561887).
  * Update OpenSSH FAQ to revision 1.110.
  * Remove ssh/new_config, only needed for direct upgrades from potato which
    are no longer particularly feasible anyway (closes: #420682).
  * Cope with insserv reordering of init script links.
  * Remove init script stop link in rc1, as killprocs handles it already.
  * Adjust short descriptions to avoid relying on previous experience with
    rsh, based on suggestions from Reuben Thomas (closes: #512198).
  * Remove manual page references to login.conf, which aren't applicable on
    non-BSD systems (closes: #154434).
  * Remove/adjust manual page references to BSD-specific /etc/rc (closes:
    #513417).
  * Refer to sshd_config(5) rather than sshd(8) in postinst-written
    /etc/ssh/sshd_config, and add UsePAM commentary from upstream-shipped
    configuration file (closes: #415008, although unfortunately this will
    only be conveniently visible on new installations).
  * Include URL to OpenBSD's ssl(8) in ssh(1), since I don't see a better
    source for the same information among Debian's manual pages (closes:
    #530692, LP: #456660).
