qpid-proton: TLS Man in the Middle Vulnerability

A cryptographic weakness was discovered in qpid-proton's use of TLS. If the qpid-proton client was used without client certificates, it would accept an anonymous cipher offered by the server. A man-in-the-middle attacker could use this to silently intercept traffic that should have been encrypted...
