A vulnerability in Cisco SIP IP Phone Software for Cisco IP Phone 7800 Series and 8800 Series could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected phone. The vulnerability is due to insufficient validation of input Session Initiation Protocol (SIP) packets.
