Ubuntu Security Notice USN-683-1
2nd December, 2008
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 8.10
- Ubuntu 8.04 LTS
- Ubuntu 7.10
- Ubuntu 6.06 LTS
It was discovered that Imlib2 did not correctly handle certain malformed
XPM images. If a user were tricked into opening a specially crafted image
with an application that uses Imlib2, an attacker could cause a denial of
service and possibly execute arbitrary code with the user's privileges.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 8.10:
- libimlib2 1.4.0-1.1ubuntu1.1
- Ubuntu 8.04 LTS:
- libimlib2 1.4.0-1ubuntu1.1
- Ubuntu 7.10:
- libimlib2 22.214.171.124debian1-4ubuntu0.1
- Ubuntu 6.06 LTS:
- libimlib2 1.2.1-2ubuntu0.3
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 Imlib2 to effect the necessary changes.
