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
