Advisory ID: RHSA-2017:1868-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2017:1868
Issue date: 2017-08-01
CVE Names: CVE-2014-9365
=====================================================================

1. Summary:

An update for python is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact
of Moderate. 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.

3. Description:

Python is an interpreted, interactive, object-oriented programming
language, which includes modules, classes, exceptions, very high level
dynamic data types and dynamic typing. Python supports interfaces to many
system calls and libraries, as well as to various windowing systems.

Security Fix(es):

* The Python standard library HTTP client modules (such as httplib or
urllib) did not perform verification of TLS/SSL certificates when
connecting to HTTPS servers. A man-in-the-middle attacker could use this
flaw to hijack connections and eavesdrop or modify transferred data.
(CVE-2014-9365)

Note: The Python standard library was updated to enable certificate
verification by default. Refer to the Knowledgebase article 2039753 linked
to in the References section for further details about this change.
(BZ#1219110)

Additional Changes:

For detailed information on changes in this release, see the Red Hat
Enterprise Linux 7.4 Release Notes linked from the References section.
