Cisco IOS OSPF Neighbor Buffer Overflow Vulnerability

Cisco IOS is prone to a remotely exploitable buffer overflow condition when handling malformed OSPF (Open Shortest Path First) packets. The overflow occurs when more than 255 OSPF neighbors are announced. This may make it possible to execute malicious instructions on a device running a vulnerable version of the software. Denial of service is also possible.

This issue corresponds to Cisco Bug ID CSCdp58462.
