Description

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
