Synopsis
========

A buffer overflow in the XRender extension 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 miscalculates the size of a buffer in the XRender extension.

Impact
======

An X.Org user could exploit this issue to make the X server execute
arbitrary code with elevated privileges.

Workaround
==========

There is no known workaround at this time.

Resolution
