USN-403-1: X.org vulnerabilities

9 January 2007

X.org vulnerabilities

Releases

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.
