Ubuntu Security Notice USN-1502-1
July 11, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
The X.Org X server could be made to crash if a specially crafted input
device was added.
- xorg-server: X.Org X server
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.
The problem can be corrected by updating your system to the following
Ubuntu 12.04 LTS:
After a standard system update you need to reboot your computer to make
all the necessary changes.
