"Several vulnerabilities have been discovered in Quagga, a routing
daemon. The Common Vulnerabilities and Exposures project identifies
the following issues :

  - CVE-2018-5378
    It was discovered that the Quagga BGP daemon, bgpd, does
    not properly bounds check data sent with a NOTIFY to a
    peer, if an attribute length is invalid. A configured
    BGP peer can take advantage of this bug to read memory
    from the bgpd process or cause a denial of service
    (daemon crash).

  https://www.quagga.net/security/Quagga-2018-0543.txt

  - 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).

  https://www.quagga.net/security/Quagga-2018-1114.txt

  - CVE-2018-5380
    It was discovered that the Quagga BGP daemon, bgpd, does
    not properly handle internal BGP code-to-string
    conversion tables.

  https://www.quagga.net/security/Quagga-2018-1550.txt

  - 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).
