========================================================================== Ubuntu Security Notice USN-2047-1 December 03, 2013
A security issue affects these releases of Ubuntu and its derivatives:
pixman could be made to crash if it opened a specially crafted file.
Software Description: - pixman: pixel-manipulation library for X and cairo
Bryan Quigley discovered an integer underflow in pixman. If a user were tricked into opening a specially crafted file, an attacker could cause a denial of service via application crash.
The problem can be corrected by updating your system to the following package versions:
Ubuntu 13.10: libpixman-1-0 0.30.2-1ubuntu0.1
Ubuntu 13.04: libpixman-1-0 0.28.2-0ubuntu1.1
Ubuntu 12.10: libpixman-1-0 0.26.0-3ubuntu0.1
Ubuntu 12.04 LTS: libpixman-1-0 0.24.4-1ubuntu0.1
After a standard system update you need to restart your session to make all the necessary changes.
