USN-2436-1: X.Org X server vulnerabilities

9 December 2014

Several security issues were fixed in the X.Org X server.




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.

Update instructions

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

Ubuntu 14.10
Ubuntu 14.04
Ubuntu 12.04

After a standard system update you need to reboot your computer to make
all the necessary changes.
