Ubuntu Security Notice USN-466-1
30th May, 2007
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 7.04
- Ubuntu 6.10
- Ubuntu 6.06 LTS
Victor Stinner discovered that freetype did not correctly verify the
number of points in a TrueType font. If a user were tricked into using
a specially crafted font, a remote attacker could execute arbitrary code
with user privileges.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 7.04:
- libfreetype6 2.2.1-5ubuntu1.1
- Ubuntu 6.10:
- libfreetype6 2.2.1-5ubuntu0.2
- Ubuntu 6.06 LTS:
- libfreetype6 2.1.10-1ubuntu2.4
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 or
reboot your computer to effect the necessary changes.
