Background ========== The NVIDIA drivers provide X11 and GLX support for NVIDIA graphic boards. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-drivers/nvidia-drivers < 295.40 >= 295.40 Description =========== A vulnerability has been found in the way NVIDIA drivers handle read/write access to GPU device nodes, allowing access to arbitrary system memory locations. NOTE: Exposure to this vulnerability is reduced in Gentoo due to 660 permissions being used on the GPU device nodes by default. Impact ====== A local attacker could gain escalated privileges. Workaround ========== There is no known workaround at this time. Resolution ========== All NVIDIA driver users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot -v ">=x11-drivers/nvidia-drivers-295.40" References ========== [ 1 ] CVE-2012-0946 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0946 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201206-19.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.
