The remote IP telephony device is missing a vendor-supplied patch.
According to its self-reported version, the version of the Cisco
Unified IP Phone software running on the remote device does not properly
process SIP headers. By sending a specially crafted SIP header to the
device, a remote attacker may be able to cause the phone to unregister,
resulting in a denial of service condition.
