S-242: Vulnerability in Cisco IOS with OSPF, MPLS VPN, and Supervisor 32, Supervisor
Cetrain Cisco Catalyst 6500 Series and Cisco 7600 Router devices that run branches of Cisco IOS based on 12.2 can be vulnerable to a denial of service vulnerability that can prevent any traffic from entering an affected interface. The risk is LOW. Exploitation of this vulnerability may result in a blocked interface input queue, memory leak, and/or restart of the device. Repeated exploitation of this vulnerability may result in an extended denial of service.
