Summary
Red Hat Security Advisory: python-paramiko security update

Notes

Topic
An update for python-paramiko is now available for Red Hat Enterprise Linux 7. 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.
Details
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.
