Ubuntu 12.04 LTS / 14.04 LTS / 14.10 : xorg-server, xorg-server-lts-trusty vulnerabilities (USN-2436-1)

Medium Nessus Plugin ID 79852


The remote Ubuntu host is missing one or more security-related patches.


Ilja van Sprundel discovered a multitude of security issues in the X.Org X server. An attacker able to connect to an X server, either locally or remotely, could use these issues to cause the X server to crash or execute arbitrary code resulting in possible privilege escalation.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected xserver-xorg-core and / or xserver-xorg-core-lts-trusty packages.
