    <p>The NVIDIA drivers provide X11 and GLX support for NVIDIA graphic
      boards.
    </p>

  <description>
    <p>Two vulnerabilities have been discovered in NVIDIA drivers:</p>
    
    <ul>
      <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>
      <li>A buffer overflow error has been discovered in NVIDIA drivers
        (CVE-2013-0131).
      </li>
    </ul>
    
    <p>NOTE: Exposure to CVE-2012-4225 is reduced in Gentoo due to 660
      permissions being used on the GPU device nodes by default.
    </p>
  </description>
  <impact type="high">
    <p>A local attacker could gain escalated privileges.</p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All NVIDIA driver users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose
      "&gt;=x11-drivers/nvidia-drivers-304.88"
    </code>
