The remote device is missing a vendor-supplied security patch.


The Cisco Adaptive Security Appliance (ASA) software running on the remote device is affected by a remote code execution vulnerability due to an issue with allocating and freeing memory when processing a malicious XML payload. An unauthenticated, remote attacker can exploit the issue to cause a reload of the affected system or to remotely execute code.
