"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).

https://www.quagga.net/security/Quagga-2018-1975.txt

For Debian 7 'Wheezy', these problems have been fixed in version
0.99.22.4-1+wheezy3+deb7u3.

We recommend that you upgrade your quagga packages.
