Description

A vulnerability in the TCP state machine of Cisco RF Gateway 1 devices could allow an unauthenticated remote attacker to prevent an affected device from delivering switched digital video (SDV) or video on demand (VoD) streams resulting in a denial of service (DoS) condition. The vulnerability is due to a processing error with TCP connections to the affected device. An attacker could exploit this vulnerability by establishing a large number of TCP connections to an affected device and not actively closing those TCP connections.
