Tim Wojtulewicz of Corelight reports:

Receiving DNS responses from async DNS requests (via A specially-crafted stream of FTP packets containing a command reply with many intermediate lines can cause Zeek to spend a large amount of time processing data.

A specially-crafted set of packets containing extremely large file offsets cause cause the reassembler code to allocate large amounts of memory.

The DNS manager does not correctly expire responses that don't contain any data, such those containing NXDOMAIN or NODATA status codes. This can lead to Zeek allocating large amounts of memory for these responses and never deallocating them.

A specially-crafted stream of RDP packets can cause Zeek to spend large protocol validation.

A specially-crafted stream of SMTP packets can cause Zeek to spend large amounts of time processing data.

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.

Tim Wojtulewicz of Corelight reports:

Fix an issue where a specially-crafted FTP packet can cause Zeek to spend large amounts of time attempting to search for valid commands in the data stream.

Fix a possible overflow in the Zeek dictionary code that may lead to a memory leak.

Fix an issue where a specially-crafted packet can cause Zeek to spend large amounts of time reporting analyzer violations.

Fix a possible assert and crash in the HTTP analyzer when receiving a specially crafted packet.

Fix an issue where a specially-crafted HTTP or SMTP packet can cause Zeek to spend a large amount of time attempting to search for filenames within the packet data.

7a425536-74f7-4ce4-9768-0079a9d44d11zeek -- potential DoS vulnerabilities

Tim Wojtulewicz of Corelight reports:

Receiving DNS responses from async DNS requests (via the lookup_addr, etc BIF methods) with the TTL set to zero could cause the DNS manager to eventually stop being able to make new requests.

Specially-crafted FTP packets with excessively long usernames, passwords, or other fields could cause log writes to use large amounts of disk space.

The find_all and find_all_ordered BIF methods could take extremely large amounts of time to process incoming data depending on the size of the input.

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.
