Cisco IOS is reported prone to a remote denial of service vulnerability. It is reported that the vulnerability manifests when a malformed Open Shortest Path First (OSPF) packet is handled by the vulnerable router. A remote attacker may exploit this condition in multiple routers that reside on the same network segment as the attacker, to trigger a device reset. The attacker may continuously transmit malicious OSPF packets to the target routers in order to effectively deny network services to legitimate hosts.
