The vulnerability is due to improper handling of SIP packets inspected by the Cisco Adaptive Security Appliance (ASA) SIP inspection engine. An attacker could exploit this vulnerability by sending crafted SIP packets through the affected system. An exploit could allow the attacker to cause allocated memory not to be returned during the attack. This may cause system instability and a partial denial of service (DoS) condition.
