USN-2014-1: OpenSSH vulnerability
Ubuntu Security Notice USN-2014-1
8th November, 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.10
OpenSSH could be made to run programs if it received specially crafted network traffic from an authenticated user.
- openssh - secure shell (SSH) client, for secure access to remote machines
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.
The problem can be corrected by updating your system to the following package version:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
