The python-paramiko package provides a Python module that implements the

machines. Unlike SSL, the SSH2 protocol does not require hierarchical
certificates signed by a powerful central authority. The protocol also
includes the ability to open arbitrary channels to remote services across
an encrypted tunnel.
Security Fix(es):
* python-paramiko: Authentication bypass in auth_handler.py
(CVE-2018-1000805)
