Synopsis
========
A buffer overflow vulnerability has been discovered in Imlib2.

Background
==========
Imlib2 is replacement library from the Enlightenment project for
libraries like libXpm.

Affected packages
=================
-------------------------------------------------------------------=
Package / Vulnerable / Unaffected
-------------------------------------------------------------------=
1 media-libs/imlib2 < 1.4.2-r1 >= 1.4.2-r=1

Description
===========
Julien Danjou reported a pointer arithmetic error and a heap-based
buffer overflow within the load() function of the XPM image loader.

Impact
======
A remote attacker could entice a user to process a specially crafted
XPM image, possibly resulting in the remote execution of arbitrary code
with the privileges of the user running the application, or a Denial of
Service.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All Imlib2 users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/imlib2-1.4.2-r1"=

References
