Synopsis
========
A new vulnerability has been discovered in libXpm, which is included in
X.org, that can potentially lead to remote code execution.
Background
==========
libXpm is a pixmap manipulation library for the X Window System,
included in X.org.
Affected packages

Description
===========
Chris Gilbert has discovered potentially exploitable buffer overflow
cases in libXpm that weren't fixed in previous libXpm versions.
Impact
======
A carefully-crafted XPM file could crash X.org, potentially allowing
the execution of arbitrary code with the privileges of the user running
the application.
Workaround
==========
There is no known workaround at this time.
