This release fixes two vulnerabilities:
- 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.
Other fixes:
- The highwayhash submodule was updated to fix a build failure on
FreeBSD 14.
- Packet sources that don't have a selectable file descriptor could
potentially prevent the network time from ever updating, which
would have adverse effects on the primary run loop such as
preventing timers from executing.
- Specific conditions in the run loop could lead RotationTimers
to get into an infinite loop.
- Specially crafted HTTP packets could avoid the HTTP analyzer.
- Zeekctl crashes using the zeekctl status command if the
StatusCmdShowAll option is set to 1 in zeekctl.cfg.
- The ignore_checksum_nets option does not work correctly if
configured with multiple subnets.
