CVE-2019-12175

In Zeek Network Security Monitor formerly known as Bro before 2.6.2, a NULL pointer dereference in the Kerberos aka KRB protocol parser leads to DoS because a case-type index is mishandled...

Zeek 8.0.4

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 ha...
