Background ========= GraphicsMagick is a collection of tools to read, write and manipulate images in many formats. GraphicsMagick is originally derived from ImageMagick 5.5.2. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/graphicsmagick < 1.1.5 > = 1.1.5 Description ========== Andrei Nigmatulin discovered that handling a Photoshop Document (PSD) file with more than 24 layers in ImageMagick could trigger a heap overflow (GLSA 200501-26). GraphicsMagick is based on the same code and therefore suffers from the same flaw. Impact ===== An attacker could potentially design a malicious PSD image file to cause arbitrary code execution with the permissions 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-1.1.5" References ========= [ 1 ] CAN-2005-0005 https://www.cve.org/CVERecord?id=CVE-CAN-2005-0005 [ 2 ] GLSA 200501-26 https://security.gentoo.org/glsa/200501-26 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200501-37 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.
