Cisco Adaptive Security Appliance (ASA) Software versions for symmetric multi-processor (SMP) platforms contain a vulnerability that could allow an unauthenticated, remote attacker to trigger the device to crash.
The vulnerability is due to the SSL/TLS certificate handling code. An attacker could exploit this vulnerability by generating a heavy SSL/TLS traffic load, which under selected circumstances may trigger the crash.
