Red Hat Product Security has rated this update as having a security
impact of Critical. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The python-paramiko package provides a Python module that implements
the SSH2 protocol for encrypted and authenticated connections to
remote 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)

For more details about the security issue(s), including the impact, a
CVSS score, and other related information, refer to the CVE page(s)
listed in the References section.
