    <p>
    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.

    <p>
    Rapid7 reported a boundary error in the NVIDIA binary graphics driver
    that leads to a buffer overflow in the accelerated rendering
    functionality.
    </p>
  </description>
  <impact type="high">
    <p>
    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.
    </p>
  </impact>
  <workaround>
    <p>
    Disable the accelerated rendering functionality in the Device section
    of xorg.conf :
    </p>
    <code>Option      "RenderAccel" "false"</code>
  </workaround>
  <resolution>
    <p>
    NVIDIA binary graphics driver users should upgrade to the latest
    version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=x11-drivers/nvidia-drivers-1.0.8776"</code>
  </resolution>
