Background

Both ImageMagick and GraphicsMagick are collection of tools to read, write and manipulate images in many formats.

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

Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.2.2.3"
