D-Link IP Fragment Denial Of Service Vulnerability

The DLink Dl-704 is a DSL/Cable router and switch designed for home network use.

A problem has been discovered in the Dl-704 router. Upon receiving a high amount of fragmented IP packets, the router begins to become resource starved. After receiving these packets for a period greater than two minutes, the router will become unstable, ceasing operation.

This results in a denial of service users on either side of the router. A power cycling is required to resume normal operation.
