SUMMARY

<http://www.quagga.net/> Quagga is "a routing software suite. Quagga bgpd
implements the BGP routing protocol". There are two vulnerabilities in the
Quagga prodcut. In both vulnerabilies, the attacker must be a configured
peer.

parameters length (or vice versa) from a configured peer can cause a
assertion failure in the stream library.

* An empty or malformed COMMUNITIES attribute in an UPDATE from a
configured peer can cause a NULL pointer dereference when the attribute is
