Summary
=======

A vulnerability in the SSL/TLS functions of the Cisco ACE30 Application Control Engine Module and the Cisco ACE 4700 Series Application Control Engine Appliances could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on the affected device.

The vulnerability is due to incomplete input validation checks in the SSL/TLS code. An attacker could exploit this vulnerability by sending specific SSL/TLS packets to the affected device. An exploit could allow the attacker to trigger a reload of the affected device.
