Synopsis
========
Multiple buffer overflows have been discovered in ImageMagick, which
could potentially result in the execution of arbitrary code.
Background
==========
ImageMagick is a free software suite to manipulate, convert, and create
many image formats.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/imagemagick < 6.2.9.5 >= 6.2.9.5
Description
===========
Tavis Ormandy of the Google Security Team discovered a stack and heap
buffer overflow in the GIMP XCF Image decoder and multiple heap and
integer overflows in the SUN bitmap decoder. Damian Put discovered a
heap overflow in the SGI image decoder.
Impact
======
An attacker may be able to create a specially crafted image that, when
processed with ImageMagick, executes arbitrary code with the privileges
of the executing user.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All ImageMagick users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.2.9.5"
