Description

A vulnerability has been discovered and fixed in libxext :

There's a race condition in libXext that causes apps that use the X shared memory extensions to occasionally crash.

Packages for 2008.0 and 2009.0 are provided due to the Extended Maintenance Program for those products.

The corrected packages solves this problem.
