CVE-2016-0739 describes a vulnerability in libssh versions prior to 0.7.3, affecting products like Canonical, Debian, and Red Hat. This flaw, a "bits/bytes confusion bug," improperly truncates ephemeral secrets for Diffie-Hellman key exchange methods, making SSH sessions vulnerable to decryption or interception by man-in-the-middle attackers. With a CVSS score of 5.9 (Medium), it has a network attack vector and high attack complexity, but could lead to high confidentiality impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
