Cisco IOS Software Resource Reservation Protocol Interface Queue Wedge Vulnerability (cisco-sa-20130925-rsvp)

High Nessus Plugin ID 70313


The remote device is missing a vendor-supplied security patch.


The remote device is affected by a denial of service vulnerability due to improper handling of UDP RSVP packets in the Resource Reservation Protocol (RSVP) feature. An unauthenticated, remote attacker, via specially-crafted UDP RSVP packets sent to port 1698, can trigger an interface queue wedge, resulting in a loss of connectivity, loss of routing protocol adjacency, and other denial of service conditions.


Apply the relevant patch referenced in Cisco Security Advisory cisco-sa-20130925-rsvp. Alternatively, apply the workaround referenced in the advisory.
