fglrx-installer vulnerability

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

Details

Marko Lindqvist discovered that the fglrx installer created an unsafe
LD_LIBRARY_PATH on 64bit systems. If a user were tricked into downloading
specially crafted libraries and running commands in the same directory,
a remote attacker could execute arbitrary code with user privileges.

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

Ubuntu 8.10:
xorg-driver-fglrx 2:8.543-0ubuntu4.1

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

After a standard system upgrade you need to restart your session to effect
the necessary changes.
