===========================================================
Ubuntu Security Notice USN-721-1          February 17, 2009
fglrx-installer vulnerability
https://launchpad.net/bugs/323327
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 8.10

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

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

Details follow:

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.


Updated packages for Ubuntu 8.10:
