The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 386a14bb-1a21-41c6-a2cf-08d79213379b advisory.

 - Tim Wojtulewicz of Corelight reports: A specially-crafted SSL packet could cause Zeek to leak memory and potentially crash. A specially-crafted series of FTP packets could cause Zeek to log entries for requests that have already been completed, using resources unnecessarily and potentially causing Zeek to lose other traffic. A specially-crafted series of SSL packets could cause Zeek to output a very large number of unnecessary alerts for the same record. A specially-crafted series of SSL packets could cause Zeek to generate very long ssl_history fields in the ssl.log, potentially using a large amount of memory due to unbounded state growth A specially-crafted IEEE802.11 packet could cause Zeek to overflow memory and potentially crash (386a14bb-1a21-41c6-a2cf-08d79213379b)
