(Quagga: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Quagga. Please review
      the CVE identifiers referenced below for details.
  
Impact :

    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.
  
Workaround :

    There is no known workaround at this time."
