Background ========== imlib is an advanced replacement library for image manipulation libraries like libXpm. It is called by numerous programs, including gkrellm and several window managers, to help in displaying images. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/imlib <= 1.9.14-r2 >= 1.9.14-r3 Description =========== Pavel Kankovsky discovered that several overflows found in the libXpm library (see GLSA 200409-34) also applied to imlib. He also fixed a number of other potential flaws. Impact ====== A remote attacker could entice a user to view a carefully-crafted image file, which would potentially lead to execution of arbitrary code with the rights of the user viewing the image. This affects any program that makes use of the imlib library. Workaround ========== There is no known workaround at this time. Resolution ========== All imlib users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/imlib-1.9.14-r3" References ========== [ 1 ] GLSA 200409-34 http://www.gentoo.org/security/en/glsa/glsa-200409-34.xml [ 2 ] CAN-2004-1026 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-1026 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200412-03.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.
