Title: Cisco IOS OSPF Neighbor Buffer Overflow Vulnerability

Severity: CRITICAL

Description:

A buffer overflow has been reported in the Cisco IOS implementation of the OSPF (Open Shortest Path First) routing protocol.

Cisco IOS is prone to a remotely exploitable buffer overflow condition when handling malformed OSPF packets. The overflow occurs when more than 255 OSPF neighbors are announced. This will cause a local IO memory structure on a device running the software to be corrupted, potentially with attacker-supplied data.

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.
