"A vulnerability in the local malware analysis process of Cisco Firepower Threat Defense (FTD) Software could allow an 
unauthenticated, remote attacker to cause a denial of service (DoS) condition on the affected device. This 
vulnerability is due to insufficient error handling in the local malware analysis process of an affected device. An 
attacker could exploit this vulnerability by sending a crafted file through the device. A successful exploit could 
allow the attacker to cause the local malware analysis process to crash, which could result in a DoS condition. Notes: 
Manual intervention may be required to recover from this situation. Malware cloud lookup and dynamic analysis will not 
be impacted.

Please see the included Cisco BID and Cisco Security Advisory for more information.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
