A vulnerability in the Cisco Discovery Protocol processing feature of Cisco IP Phone 7800 and 8800 Series firmware could allow an unauthenticated, adjacent attacker to cause a stack overflow on an affected device. This vulnerability is due to insufficient input validation of received Cisco Discovery Protocol packets.
