  script_set_attribute(attribute:"description", value:
"A vulnerability in the call-handling functionality of Session
Initiation Protocol (SIP) Software for Cisco IP Phone 7800 Series and
8800 Series could allow an unauthenticated, remote attacker to cause
an affected phone to reload unexpectedly, resulting in a temporary
denial of service (DoS) condition. The vulnerability is due to
incomplete error handling when XML data within a SIP packet is parsed.
An attacker could exploit this vulnerability by sending a SIP packet
that contains a malicious XML payload to an affected phone. A
successful exploit could allow the attacker to cause the affected
phone to reload unexpectedly, resulting in a temporary DoS condition.
