========================================================================== Ubuntu Security Notice USN-1502-1 July 11, 2012
xorg-server vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Summary:
The X.Org X server could be made to crash if a specially crafted input device was added.
Software Description: - xorg-server: X.Org X server
Details:
Ken Mixter discovered a format string vulnerability in the LogVHdrMessageVerb function when handling input device names. This could allow a local attacker to cause a denial of service or possibly execute arbitrary code.
The default compiler options for the affected release should reduce the vulnerability to a denial of service.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 LTS: xserver-xorg-core 2:1.11.4-0ubuntu10.5
After a standard system update you need to reboot your computer to make all the necessary changes.
