Description
Tim Wojtulewicz of Corelight reports: A missing field in the SMB FSControl script-land record could cause a heap buffer overflow when receiving packets containing those header types. Receiving a series of packets that start with HTTP/1.0 and then switch to HTTP/0.9 could cause Zeek to spend a large amount of time processing the packets. Receiving large numbers of FTP commands sequentially from the network with bad data in them could cause Zeek to spend a large amount of time processing the packets, and generate a large amount of events.
