1 December 2008

libvorbis vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 8.04 LTS
  • Ubuntu 7.10
  • Ubuntu 6.06 LTS

Software Description

  • libvorbis

Details

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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

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.
