Releases

• Ubuntu 6.10
• Ubuntu 6.06
• Ubuntu 5.10

Details

The DBE and Render extensions in X.org were vulnerable to integer
overflows, which could lead to memory overwrites. An authenticated user
could make a specially crafted request and execute arbitrary code with
root privileges.

Update instructions

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

Ubuntu 6.10

• xserver-xorg-core - 1:1.1.1-0ubuntu12.1

Ubuntu 6.06

• xserver-xorg-core - 1:1.0.2-0ubuntu10.5

Ubuntu 5.10

• xserver-xorg-core - 6.8.2-77.2

After a standard system upgrade you need to reboot your computer to
effect the necessary changes.
