Cisco has warned in a security advisory that some networks with its routers could be vulnerable to denial-of-service attacks.
The problem is in the processing of packets sent to a Cisco router that has been configured for the Open Shortest Path First (OSPF) protocol, the company said in a security advisory released Wednesday. If the router receives a malformed packet, it will take a while to reset. Attackers could flood networks with packets that cause routers to constantly reboot. The flaw is limited to versions 12.0S, 12.2 and 12.3 of Cisco's Internetwork Operating System routing software. Jon Oltsik, a network security analyst at the Enterprise Strategy Group, said the vulnerable versions and configuration are in common use and that the effects of a successful attack could be devastating to an enterprise.
