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: http://security.gentoo.org/glsa/glsa-200505-16.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
