Ubuntu Security Notice USN-643-1
11th September, 2008
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 8.04 LTS
- Ubuntu 7.10
- Ubuntu 7.04
- Ubuntu 6.06 LTS
Multiple flaws were discovered in the PFB and TTF font handling code
in freetype. If a user were tricked into using a specially crafted
font file, a remote attacker could execute arbitrary code with user
privileges or cause the application linked against freetype to crash,
leading to a denial of service.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 8.04 LTS:
- libfreetype6 2.3.5-1ubuntu4.8.04.1
- Ubuntu 7.10:
- libfreetype6 2.3.5-1ubuntu126.96.36.199
- Ubuntu 7.04:
- libfreetype6 2.2.1-5ubuntu1.2
- Ubuntu 6.06 LTS:
- libfreetype6 2.1.10-1ubuntu2.5
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system upgrade you need to restart your session to
effect the necessary changes.
