While investigating bug PROTON-2014, we discovered that under some circumstances Apache Qpid Proton versions 0.9 to 0.27.0 (C library and its language bindings) can connect to a peer anonymously using TLS *even when configured to verify the peer certificate* while used with OpenSSL versions before 1.1.0. This means that an undetected man in the middle attack could be constructed if an attacker can arrange to intercept TLS traffic.

The qpidd broker in Apache Qpid 0.30 and earlier allows remote authenticated users to cause a denial of service (daemon crash) via an AMQP message with (1) an invalid range in a sequence set, (2) content-bearing methods other than message-transfer, or (3) a session-gap control before a corresponding session-attach.

The Python client in Apache Qpid before 2.2 does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

The serializing/deserializing functions in the qpid::framing::Buffer class in Apache Qpid 0.20 and earlier allow remote attackers to cause a denial of service (assertion failure and daemon exit) via unspecified vectors. NOTE: this issue could also trigger an out-of-bounds read, but it might not trigger a crash.

The default configuration for Apache Qpid 0.20 and earlier, when the federation_tag attribute is enabled, accepts AMQP connections without checking the source user ID, which allows remote attackers to bypass authentication and have other unspecified impact via an AMQP request.
