<p>The NVIDIA drivers provide X11 and GLX support for NVIDIA graphic
<p>Two vulnerabilities have been discovered in NVIDIA drivers:</p>
<li>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 (CVE-2012-4225).
<li>A buffer overflow error has been discovered in NVIDIA drivers
<p>NOTE: Exposure to CVE-2012-4225 is reduced in Gentoo due to 660
permissions being used on the GPU device nodes by default.
<impact type="high">
<p>A local attacker could gain escalated privileges.</p>
<p>There is no known workaround at this time.</p>
<p>All NVIDIA driver users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose
