Zeek 3.0.0 (Formerly Known As Bro)
Posted Oct 5, 2019
Authored by Robin Sommer, Vern Paxson | Site zeek.org

Zeek is a powerful network analysis framework that is much different from the typical IDS you may know. While focusing on network security monitoring, Zeek provides a comprehensive platform for more general network traffic analysis as well. Well grounded in more than 15 years of research, Zeek has successfully bridged the traditional gap between academia and operations since its inception. Today, it is relied upon operationally in particular by many scientific environments for securing their cyber-infrastructure. Zeek's user community includes major universities, research labs, supercomputing centers, and open-science communities.

Changes: Bro is now known as Zeek. Added support for DNSSEC resource records RRSIG, DNSKEY, DS, NSEC, and NSEC3. Added support for parsing and logging DNS SPF resource records. Various other updates.

Changes: This is a security patch release to address a potential denial of service vulnerability. The NTLM analyzer did not properly handle AV Pair sequences that were either empty or unterminated, resulting in invalid memory access or heap buffer over-read. The NTLM analyzer is enabled by default and used in the analysis of SMB, DCE/RPC, and GSSAPI protocols.

Changes: Multiple fixes and improvements to BinPAC generated code related to array parsing, with potential impact to all Bro's BinPAC-generated analyzers in the form of buffer over-reads or other invalid memory accesses depending on whether a particular analyzer incorrectly assumed that the evaluated-array-length expression is actually the number of elements that were parsed out from the input. Various other updates.

Changes: Bro 2.5.2 fixes a security issue in the ContentLine analyzer. In rare cases a bug in the ContentLine analyzer can lead to an out of bound write of a single byte. This allows a remote attacker to crash Bro; there also is a possibility this can be exploited in other ways.
