===================================================================== Red Hat Security Advisory
Synopsis: Critical: python-paramiko security and bug fix update Advisory ID: RHSA-2018:0591-01 Product: Red Hat Enterprise Linux Extras Advisory URL: https://access.redhat.com/errata/RHSA-2018:0591 Issue date: 2018-03-26 CVE Names: CVE-2018-7750 =====================================================================
1. Summary:
An update for python-paramiko is now available for Red Hat Enterprise Linux 7 Extras.
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 7 Extras - 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)
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.
Bug Fix(es):
* python-paramiko has been using the python2-pyasn1 package, but did not depend on it. With new versions of python2-cryptography, python2-pyasn1 was not getting installed and this caused python-paramiko to malfunction. This bug was fixed by making python-paramiko depend on python2-pyasn1 explicitly. (BZ#1559133)
