Synopsis :

The remote security device is missing a vendor-supplied security

Description :

The remote Cisco ASA is missing a security patch and may be affected
by a denial of service vulnerability. When SIP inspection is enabled
and SIP traffic does not establish the secondary connection, duplicate
pre-allocated secondary pinholes are created, which could cause CPU
utilization to increase. A remote, unauthenticated attacker could
exploit this to cause a denial of service.
