Synopsis
========
An integer overflow in pixmap memory allocation potentially allows any
X.Org user to execute arbitrary code with elevated privileges.
Background
==========
X.Org is X.Org Foundation's Public Implementation of the X Window
System.

Description
===========
X.Org is missing an integer overflow check during pixmap memory
allocation.
Impact
======
An X.Org user could exploit this issue to make the X server execute
arbitrary code with elevated privileges.
Workaround
