Ubuntu Security Notice USN-1686-1
14th January, 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS
FreeType could be made to crash or run programs as your login if it opened a specially crafted file.
- freetype - FreeType 2 is a font engine library
Mateusz Jurczyk discovered that FreeType did not correctly handle certain
malformed BDF font files. If a user were tricked into using a specially
crafted font file, a remote attacker could cause FreeType to crash or
possibly execute arbitrary code with user privileges.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 12.10:
- libfreetype6 2.4.10-0ubuntu1.1
- Ubuntu 12.04 LTS:
- libfreetype6 2.4.8-1ubuntu2.1
- Ubuntu 11.10:
- libfreetype6 2.4.4-2ubuntu1.3
- Ubuntu 10.04 LTS:
- libfreetype6 2.3.11-1ubuntu2.7
- Ubuntu 8.04 LTS:
- libfreetype6 2.3.5-1ubuntu4.8.04.10
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

the necessary changes.
