Synopsis
========

An integer overflow in libXpm might allow remote attackers to execute
arbitrary code or cause a Denial of Service Condition.

Background
==========

The X PixMap image format is an extension of the monochrome X BitMap
format specified in the X protocol, and is commonly used in traditional
X applications.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 x11-libs/libXpm < 3.5.12 >= 3.5.12

Description
===========

An integer overflow was discovered in libXpm's src/CrDatFrI.c file. On
64 bit systems, this allows an overflow to occur on 32 bit integers
while parsing XPM extensions in a file.

Impact
======

A remote attacker, by enticing a user to process a specially crafted
XPM file, could execute arbitrary code with the privileges of the
process or cause a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All libXpm users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-libs/libXpm-3.5.12"
