Description Jan Lieskovsky 2012-03-13 15:19:52 UTC

An assertion failure was found in the way Quagga's ospfd daemon processed certain OSPF LS-Update packets. An adjacent OSPF router could send a specially-crafted OSPF Link State Update (LS-Update) packet, which once processed would cause the vulnerable ospfd daemon to abort (denial of service).
