204f1a7a-43df-412f-ad25-7dbe88f54fa4zeek -- potential DoS vulnerabilty

Tim Wojtulewicz of Corelight reports:

Fix potential hang in the DNS analyzer when receiving a specially-crafted packet. Due to the possibility of this happening with packets received from the network, this is a potential DoS vulnerability.

bc83cfc9-42cf-4b00-97ad-d352ba0c5e2bzeek -- null-pointer dereference vulnerability

Jon Siwek of Corelight reports:

Fix null-pointer dereference when encountering an invalid enum name in a config/input file that tries to read it into a set[enum]. For those that have such an input feed whose contents may come from external/remote sources, this is a potential DoS vulnerability.

4ae135f7-85cd-4c32-ad94-358271b31f7fzeek -- potential denial of service issues

Jon Siwek of Corelight reports:

This release addresses the following security issues:

  • Potential Denial of Service due to memory leak in DNS TSIG message parsing.
  • Potential Denial of Service due to memory leak (or assertion when compiling with assertions enabled) when receiving a second SSH KEX message after a first.
  • Potential Denial of Service due to buffer read overflow and/or memory leaks in Kerberos analyzer. The buffer read overflow could occur when the Kerberos message indicates it contains an IPv6 address, but does not send enough data to parse out a full IPv6 address. A memory leak could occur when processing KRB_KDC_REQ KRB_KDC_REP messages for message types that do not match a known/expected type.
  • Potential Denial of Service when sending many zero-length SSL/TLS certificate data. Such messages underwent the full Zeek file analysis treatment which is expensive (and meaninguless here) compared to how cheaply one can "create" or otherwise indicate many zero-length contained in an SSL message.
  • Potential Denial of Service due to buffer read overflow in SMB transaction data string handling. The length of strings being parsed from SMB messages was trusted to be whatever the message claimed instead of the actual length of data found in the message.
  • Potential Denial of Service due to null pointer dereference in FTP ADAT Base64 decoding.
  • Potential Denial of Service due buffer read overflow in FTP analyzer word/whitespace handling. This typically won't be a problem in most default deployments of Zeek since the FTP analyzer receives data from a ContentLine (NVT) support analyzer which first null-terminates the buffer used for further FTP parsing.

Jon Siwek of Corelight reports:

This release fixes the following security issues:

  • Fix potential stack overflow in NVT analyzer
  • Fix NVT analyzer memory leak from multiple telnet authn name options
  • Fix multiple content-transfer-encoding headers causing a memory leak
  • Fix potential leak of Analyzers added to tree during Analyzer::Done

a00c76d9-0c05-4d99-bef7-ae4521cb2a4dzeek -- potential DoS vulnerabilty

Tim Wojtulewicz of Corelight reports:

Fix potential unbounded state growth in the FTP analyzer when receiving a specially-crafted stream of commands. This may lead to a buffer overflow and cause Zeek to crash. Due to the possibility of this happening with packets received from the network, this is a potential DoS vulnerabilty.

a550d62c-f78d-4407-97d9-93876b6741b9zeek -- several potential DoS vulnerabilities

Tim Wojtulewicz of Corelight reports:

Fix potential Undefined Behavior in decode_netbios_name() and decode_netbios_name_type() BIFs. The latter has a possibility of a remote heap-buffer-overread, making this a potential DoS vulnerability.

Add some extra length checking when parsing mobile ipv6 packets. Due to the possibility of reading invalid headers from remote sources, this is a potential DoS vulnerability.

Jon Siwek of Corelight reports:

d4d21998-bdc4-4a09-9849-2898d9b41459zeek -- several vulnerabilities

Tim Wojtulewicz of Corelight reports:

Paths from log stream make it into system() unchecked, potentially leading to commands being run on the system unintentionally. This requires either bad scripting or a malicious package to be installed, and is considered low severity.

Fix potential unbounded state growth in the PIA analyzer when receiving a connection with either a large number of zero-length packets, or one which continues ack-ing unseen segments. It is possible to run Zeek out of memory in these instances and cause it to crash. Due to the possibility of this happening with packets received from the network, this is a potential DoS vulnerability.
