Background ========== ImageMagick is an application suite to manipulate and convert images. It is often used as a utility backend by web applications like forums, content management systems or picture galleries. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/imagemagick < 6.2.5.5 >= 6.2.5.5 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. This is a new vulnerability that is not addressed by GLSA 200503-11. Impact ====== By feeding specially crafted file names to ImageMagick, an attacker can crash the program and possibly execute arbitrary code with the privileges of the user running ImageMagick. 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-6.2.5.5" References ========== [ 1 ] CVE-2006-0082 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0082 [ 2 ] GLSA 200503-11 http://www.gentoo.org/security/en/glsa/glsa-200503-11.xml Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200602-06.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.
