### Description

A vulnerability in the XML service of Cisco IP Phone firmware could allow an unauthenticated, remote attacker to initiate phone calls on an affected device.  

 This vulnerability exists because bounds-checking does not occur while parsing XML requests. An attacker could exploit this vulnerability by sending a crafted XML request to an affected device. A successful exploit could allow the attacker to initiate calls or play sounds on the device.
