"A vulnerability in the Session Initiation Protocol (SIP) call-handling
functionality of Cisco IP Phone 7800 Series phones and Cisco IP Phone
8800 Series phones could allow an unauthenticated, remote attacker to
cause a denial of service (DoS) condition on an affected phone. The
vulnerability is due to incomplete input validation of SIP Session
Description Protocol (SDP) parameters by the SDP parser of an affected
phone. An attacker could exploit this vulnerability by sending a
malformed SIP packet to an affected phone. A successful exploit could
allow the attacker to cause all active phone calls on the affected
phone to be dropped while the SIP process on the phone unexpectedly
restarts, resulting in a DoS condition. Cisco Bug IDs: CSCvf40066.
