 > CVE-2018-5379

 >     It was discovered that the Quagga BGP daemon, bgpd, can double-free
 >     memory when processing certain forms of UPDATE message, containing
 >     cluster-list and/or unknown attributes, resulting in a denial of
 >     service (bgpd daemon crash).

 > CVE-2018-5380

 >     It was discovered that the Quagga BGP daemon, bgpd, does not
 >     properly handle internal BGP code-to-string conversion tables.

 > CVE-2018-5381

 >     It was discovered that the Quagga BGP daemon, bgpd, can enter an
 >     infinite loop if sent an invalid OPEN message by a configured peer.
 >     A configured peer can take advantage of this flaw to cause a denial
 >     of service (bgpd daemon not responding to any other events; BGP
 >     sessions will drop and not be reestablished; unresponsive CLI
 >     interface).
