  <background>
    <p>Quagga is a free routing daemon replacing Zebra supporting RIP, OSPF and
      BGP.

  <description>
    <p>Multiple vulnerabilities have been discovered in Quagga. Please review
      the CVE identifiers referenced below for details.
    </p>
  </description>
  <impact type="high">
    <p>A BGP peer could send a Route-Refresh message with specially-crafted ORF
      record, which can cause Quagga's bgpd to crash or possibly execute
      arbitrary code with the privileges of the user running Quagga's bgpd; a
      BGP update AS path request with unknown AS type, or malformed
      AS-Pathlimit or Extended-Community attributes could lead to Denial of
      Service (daemon crash), an error in bgpd when handling AS_PATH attributes
      within UPDATE messages can
      be exploited to cause a heap-based buffer overflow resulting in a crash
      of the
      daemon and disruption of IPv4 routing, two errors in ospf6d and ospfd can
      each be exploited to crash the daemon and disrupt IP routing.
    </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>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=net-misc/quagga-0.99.20"
    </code>
