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 < 6.2.2.3 >= 6.2.2.3 2 media-gfx/graphicsmagick < 1.1.6-r1 >= 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 ">=media-gfx/imagemagick-6.2.2.3"
All GraphicsMagick users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/graphicsmagick-1.1.6-r1"
Availability ============
This GLSA and any updates to it are available for viewing at the Gentoo Security Website:
