  <description>
    <p>A memcpy function in the VPNv4 NLRI parser of bgp_mplsvpn.c does not
      properly check the upper-bound length of received Labeled-VPN SAFI routes
      data, which may allow for arbitrary code execution on the stack.
    </p>
  </description>
  <impact type="high">
    <p>A remote attacker could send a specially crafted packet, possibly
      resulting in execution of arbitrary code with the privileges of the
      process or a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All Quagga users should upgrade to the latest version:</p>
