|Description||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.|

Vulnerable and fixed packages
The table below lists information on source packages.
The information below is based on the following data on fixed versions.
|Package||Type||Release||Fixed Version||Urgency||Origin||Debian Bugs|
[stretch] - qpid-proton <no-dsa> (Minor issue)
[jessie] - qpid-proton <ignored> (Minor issue)
Source-wise only fixed in 0.27.1 upstream, but 0.22.0-1 upload in
unstable switched to build against OpenSSL 1.1 adressing the issue.
The description tells that the vulnerability was introduced in 0.9 but the
version in jessie (0.7) seems to be vulnerable too even though one file is
not present in the jessie version. That part do not seem to be essential for
the package to be vulnerable.
