Advisory ID:       RHSA-2018:1124-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2018:1124

CVE Names:         CVE-2018-7750 
=====================================================================

1. Summary:

An update for python-paramiko is now available for Red Hat Enterprise Linux
6.

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - noarch
Red Hat Enterprise Linux HPC Node (v. 6) - noarch
Red Hat Enterprise Linux Server (v. 6) - noarch
Red Hat Enterprise Linux Workstation (v. 6) - noarch

3. Description:

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 transport.py (CVE-2018-7750)
