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"
