Title: D-Link IP Fragment Denial Of Service Vulnerability
Severity: HIGH
Description:
The DLink Dl-704 is a DSL/Cable router and switch designed for home network use.
A problem in the Dl-704 may make it possible for a remote user to deny access to and from networks serviced by the router. The problem is due to the handling of fragmented IP packets.
Upon receiving a high amount of fragmented IP packets over a period of two minutes, the router becomes unstable. Typically, this traffic will consume 100 percent of the CPU, starving the system of resources.
However, after passing a period of time (reportedly two minutes), the router becomes unstable, and ceases function. The end result is the router ceasing operation, and requiring a reboot to resume normal function.
Affected Products:
- D-Link Dl-704 2.56.0 b5
