The Open Shortest Path First (OSPF) implementation in the remote Cisco IOS software versions is vulnerable to a denial of service if it receives a flood of neighbor announcements in which more than 255 hosts try to establish a neighbor relationship per interface. An attacker may use this flaw to prevent the router from working properly. This vulnerability is documented as Cisco Bug ID CSCdp58462.
