Background ========== The GD graphics library is an open source library which allows programmers to easily generate PNG, JPEG, GIF and WBMP images from many different programming languages. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/gd < 2.0.32 >= 2.0.32 Description =========== infamous41md found an integer overflow in the memory allocation procedure of the GD routine that handles loading PNG image files. Impact ====== A remote attacker could entice a user to load a carefully crafted PNG image file in a GD-powered application, or send a PNG image to a web application which uses GD PNG decoding functions. This could potentially lead to execution of arbitrary code with the rights of the program loading the image. Workaround ========== There is no known workaround at this time. Resolution ========== All GD users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/gd-2.0.32" References ========== [ 1 ] Original BugTraq advisory http://www.securityfocus.com/archive/1/379382 [ 2 ] CAN-2004-0990 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0990 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200411-08.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.
