S-244: Cisco IOS User Datagram Protocol Delivery Issue for IPv4/IPv6 Dual-Stack Route

A device running Cisco IOS software that has Internet Protocol version 6 (IPv6) enabled may be subject to a denial of service (DoS) attack. The risk is LOW. Successful exploitation of the vulnerability can result in the device crashing if RSVP service is configured on the interface or any other affected IPv4 UDP-based service will prevent the interface from receiving additional traffic.
