RHSA-2018:3406 - Security Advisory

Synopsis

Critical: python-paramiko security update

Type/Severity

Security Advisory: Critical

Topic

An update for python-paramiko is now available for Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 6.4 Advanced Update Support, Red Hat Enterprise Linux 6.5 Advanced Update Support, Red Hat Enterprise Linux 6.6 Advanced Update Support, Red Hat Enterprise Linux 6.6 Telco Extended Update Support, and Red Hat Enterprise Linux 6.7 Extended Update Support.

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.

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 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.
