==========================================================================
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.
