RHEL 7 : python (RHSA-2018:2123)

high Nessus Plugin ID 110919

Language:

Synopsis

The remote Red Hat host is missing a security update for python.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:2123 advisory.

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):

* A flaw was found in the way the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the- middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/SSL server and client if the communication used a DES/3DES based ciphersuite.
(CVE-2016-2183)

Note: This update modifies the Python ssl module to disable 3DES cipher suites by default.

Red Hat would like to thank OpenVPN for reporting this issue. Upstream acknowledges Karthikeyan Bhargavan (Inria) and Gatan Leurent (Inria) as the original reporters.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL python package based on the guidance in RHSA-2018:2123.
