Ubuntu Security Notice USN-682-1
1st December, 2008
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 8.04 LTS
- Ubuntu 7.10
- Ubuntu 6.06 LTS
It was discovered that libvorbis did not correctly handle certain malformed
sound files. If a user were tricked into opening a specially crafted sound
file with an application that uses libvorbis, an attacker could execute
arbitrary code with the user's privileges.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 8.04 LTS:
- libvorbis0a 1.2.0.dfsg-2ubuntu0.1
- Ubuntu 7.10:
- libvorbis0a 1.2.0.dfsg-1ubuntu0.1
- Ubuntu 6.06 LTS:
- libvorbis0a 1.1.2-0ubuntu2.3
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system upgrade you need to restart any applications that
use libvorbis, such as Totem and gtkpod, to effect the necessary changes.
