Synopsis
=======
ImageMagick and GraphicsMagick utilities can be abused to perform a Denial of Service attack.
Background
=========
Both ImageMagick and GraphicsMagick are collection of tools to read, write and manipulate images in many formats.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/imagemagick lt; 6.2.2.3 gt;= 6.2.2.3
2 media-gfx/graphicsmagick lt; 1.1.6-r1 gt;= 1.1.6-r1
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
==========
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a Denial of Service vulnerability in the XWD decoder of ImageMagick and GraphicsMagick when setting a color mask to zero.
Impact
=====
A remote attacker could submit a specially crafted image to a user or an automated system making use of an affected utility, resulting in a Denial of Service by consumption of CPU time.
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 "gt;=media-gfx/imagemagick-6.2.2.3"
All GraphicsMagick users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose "gt;=media-gfx/graphicsmagick-1.1.6-r1"
Availability
===========
This GLSA and any updates to it are available for viewing at the Gentoo Security Website:
http://security.gentoo.org/glsa/glsa-200505-16.xml
