Message-ID: <200501202247.02012.jaervosz@gentoo.org> From: jaervosz at gentoo.org (Sune Kloppenborg Jeppesen) Subject: [ GLSA 200501-26 ] ImageMagick: PSD decoding heap overflow - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 200501-26 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - http://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: ImageMagick: PSD decoding heap overflow Date: January 20, 2005 Bugs: #77932 ID: 200501-26 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== ImageMagick is vulnerable to a heap overflow when decoding Photoshop Document (PSD) files, which could lead to arbitrary code execution. Background ========== ImageMagick is a collection of tools to read, write and manipulate images in many formats. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/imagemagick < 6.1.8.8 >= 6.1.8.8 Description =========== Andrei Nigmatulin discovered that a Photoshop Document (PSD) file with more than 24 layers could trigger a heap overflow. Impact ====== An attacker could potentially design a mailicous PSD image file to cause arbitrary code execution with the permissions 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-6.1.8.8" References ========== [ 1 ] CAN-2005-0005 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0005 [ 2 ] iDEFENSE Advisory http://www.idefense.com/application/poi/display?id=184&type=vulnerabilities Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200501-26.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.
