imlib2 vulnerability

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

  • Ubuntu 8.04 LTS
  • Ubuntu 7.10
  • Ubuntu 6.06 LTS

Software Description

  • imlib2

Details

It was discovered that Imlib2 did not correctly handle certain malformed XPM and PNG 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.

Update instructions

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

Ubuntu 8.04 LTS
libimlib2 - 1.4.0-1ubuntu1.2
Ubuntu 7.10
libimlib2 - 1.3.0.0debian1-4ubuntu0.2
Ubuntu 6.06 LTS
libimlib2 - 1.2.1-2ubuntu0.4

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.
