Ubuntu Security Notice USN-2014-1

openssh vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.10

Summary:

OpenSSH could be made to run programs if it received specially crafted
network traffic from an authenticated user.

Software Description:
- openssh: secure shell (SSH) client, for secure access to remote machines

Details:

Markus Friedl discovered that OpenSSH incorrectly handled memory when the
AES-GCM cipher was used. A remote authenticated attacker could use this
issue to execute arbitrary code as their user, possibly bypassing
shell or command restrictions.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 13.10:
  openssh-server                  1:6.2p2-6ubuntu0.1

In general, a standard system update will make all the necessary changes.
