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

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"
