Background ========== The NVIDIA binary graphics driver from NVIDIA Corporation provides the kernel module and the GL modules for graphic acceleration on the NVIDIA based graphic cards. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-drivers/nvidia-drivers < 1.0.8776 >= 1.0.8776 < 1.0-8762 Description =========== Rapid7 reported a boundary error in the NVIDIA binary graphics driver that leads to a buffer overflow in the accelerated rendering functionality. Impact ====== An X client could trigger the buffer overflow with a maliciously crafted series of glyphs. A remote attacker could also entice a user to open a specially crafted web page, document or X client that will trigger the buffer overflow. This could result in the execution of arbitrary code with root privileges or at least in the crash of the X server. Workaround ========== Disable the accelerated rendering functionality in the Device section of xorg.conf : Option "RenderAccel" "false" Resolution ========== NVIDIA binary graphics driver users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=x11-drivers/nvidia-drivers-1.0.8776" References ========== [ 1 ] CVE-2006-5379 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-5379 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200611-03.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.
