Bro is a powerful network analysis framework that is much different from the typical IDS you may know. While focusing on network security monitoring, Bro provides a comprehensive platform for more general network traffic analysis as well. Well grounded in more than 15 years of research, Bro 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. Bro's user community includes major universities, research labs, supercomputing centers, and open-science communities.

Qualys has discovered that OpenBSD suffers from multiple authentication bypass and local privilege escalation vulnerabilities.

Qualys discovered a local privilege escalation in OpenBSD's dynamic loader (ld.so). This vulnerability is exploitable in the default installation (via the set-user-ID executable chpass or passwd) and yields full root privileges. They developed a simple proof of concept and successfully tested it against OpenBSD 6.6 (the current release), 6.5, 6.2, and 6.1, on both amd64 and i386; other releases and architectures are probably also exploitable.

This Metasploit module exploits a vulnerability in the OpenBSD ld.so dynamic loader (CVE-2019-19726). The _dl_getenv() function fails to reset the LD_LIBRARY_PATH environment variable when set with approximately ARG_MAX colons. This can be abused to load libutil.so from an untrusted path, using LD_LIBRARY_PATH in combination with the chpass set-uid executable, resulting in privileged code execution. This module has been tested successfully on OpenBSD 6.1 (amd64) and OpenBSD 6.6 (amd64).
