Background ========== Blender is an open source software for 3D modeling, animation, rendering, post-production, interactive creation and playback. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/blender < 2.40 >= 2.40 Description =========== Damian Put has reported a flaw due to an integer overflow in the "get_bhead()" function, leading to a heap overflow when processing malformed ".blend" files. Impact ====== A remote attacker could entice a user into opening a specially crafted ".blend" file, resulting in the execution of arbitrary code with the permissions of the user running Blender. Workaround ========== There is no known workaround at this time. Resolution ========== All Blender users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/blender-2.40" References ========== [ 1 ] CVE-2005-4470 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-4470 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200601-08.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.
