Background ========== ImageMagick is a free software suite to manipulate, convert, and create many image formats. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/imagemagick < 6.2.9.5 >= 6.2.9.5 Description =========== Tavis Ormandy of the Google Security Team discovered a stack and heap buffer overflow in the GIMP XCF Image decoder and multiple heap and integer overflows in the SUN bitmap decoder. Damian Put discovered a heap overflow in the SGI image decoder. Impact ====== An attacker may be able to create a specially crafted image that, when processed with ImageMagick, executes arbitrary code with the privileges of the executing user. 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-6.2.9.5" References ========== [ 1 ] CVE-2006-3743 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3743 [ 2 ] CVE-2006-3744 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3744 [ 3 ] CVE-2006-4144 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4144 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200609-14.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.
