Background ========== GraphicsMagick is a collection of tools to read, write and manipulate images in many formats. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/graphicsmagick < 1.1.7 >= 1.1.7 Description =========== The SetImageInfo function was found vulnerable to a format string mishandling. Daniel Kobras discovered that the handling of "%"-escaped sequences in filenames passed to the function is inadequate in ImageMagick GLSA 200602-06 and the same vulnerability exists in GraphicsMagick. Impact ====== By feeding specially crafted file names to GraphicsMagick an attacker can crash the program and possibly execute arbitrary code with the privileges of the user running GraphicsMagick. Workaround ========== There is no known workaround at this time. Resolution ========== All GraphicsMagick users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/graphicsmagick-1.1.7" References ========== [ 1 ] GLSA 200602-06 http://www.gentoo.org/security/en/glsa/glsa-200602-06.xml Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200602-13.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.
