Description



Tim Wojtulewicz of Corelight reports:



A specially-crafted series of FTP packets with a CMD


command with a large path followed by a very large number


of replies could cause Zeek to spend a long time processing


the data.


A specially-crafted with a truncated header can cause


Zeek to overflow memory and potentially crash.


A specially-crafted series of SMTP packets can cause


Zeek to generate a very large number of events and take


a long time to process them.


A specially-crafted series of POP3 packets containing


MIME data can cause Zeek to spend a long time dealing


with each individual file ID.
