USN-2438-1: NVIDIA graphics drivers vulnerabilities

10 December 2014

Several security issues were fixed in the NVIDIA graphics drivers.




It was discovered that the NVIDIA graphics drivers incorrectly handled GLX
indirect rendering support. 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.
