Description

An update for python-paramiko is now available for Red Hat Virtualization 4 Management Agent for RHEL 7 and Red Hat Virtualization Manager 4.1.

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.

The following packages have been upgraded to a later upstream version:
python-paramiko (2.1.1). (BZ#1562393)

Security Fix(es) :

* python-paramiko: Authentication bypass in transport.py (CVE-2018-7750)

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.
