Background ========== ImageMagick is a collection of tools and libraries for manipulating a wide variety of image formats. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/imagemagick < 6.2.0.4 >= 6.2.0.4 Description =========== Tavis Ormandy of the Gentoo Linux Security Audit Team has identified a flaw in the handling of filenames by the ImageMagick utilities. Impact ====== Successful exploitation may disrupt web applications that depend on ImageMagick for image processing, potentially executing arbitrary code. 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-6.2.0.4" Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200503-11.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.
