Upstream CVE-2011-3324 patch for Quagga-master branch none

Description Jan Lieskovsky 2011-09-14 17:26:01 UTC 
A denial of service flaw was found in the way the ospf6d daemon of the Quagga routing suite processed certain Database Description packets with specially-crafted Link-State-Advertisement (LSA). A configured OSPF peer, could use this flaw to cause the denial of the master OSPF router service (ospf6d termination due to assertion failure) via Database Description packet with trailing zero octets.
