Synopsis
========
Two vulnerabilities in Imlib 2 may allow for the execution of arbitrary
code.
Background
==========
Imlib 2 is an advanced replacement library for libraries like libXpm.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/imlib2 < 1.4.0-r1 >= 1.4.0-r1
Description
===========
Stefan Cornelius (Secunia Research) reported two boundary errors in
Imlib2:
* One of them within the load() function in the file
src/modules/loaders/loader_pnm.c when processing the header of a PNM
image file, possibly leading to a stack-based buffer overflow.
* The second one within the load() function in the file
src/modules/loader_xpm.c when processing an XPM image file, possibly
leading to a stack-based buffer overflow.
Impact
======
A remote attacker could entice a user to open a specially crafted PNM
or XPM image, possibly resulting in the execution of arbitrary code
with the rights of the user running the application using Imlib 2.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Imlib 2 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/imlib2-1.4.0-r1"
