User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Ubuntu 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.
===========================================================
Ubuntu Security Notice USN-697-1          December 22, 2008
imlib2 vulnerability
CVE-2008-2426
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 7.10
Ubuntu 8.04 LTS

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

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

Ubuntu 6.06 LTS:
  libimlib2                       1.2.1-2ubuntu0.4

Ubuntu 7.10:
  libimlib2                       1.3.0.0debian1-4ubuntu0.2

Ubuntu 8.04 LTS:
  libimlib2                       1.4.0-1ubuntu1.2

After a standard system upgrade you need to restart any applications that
use Imlib2 to effect the necessary changes.

Details follow:

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.
