Summary

A vulnerability in the Session Initiation Protocol (SIP) inspection engine 
code could allow an unauthenticated, remote attacker to cause a slow memory 
leak, which may cause instability on the affected system.

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.
