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.
