RHEL 8 : python39:3.9 and python39-devel:3.9 (RHSA-2023:2764)

high Nessus Plugin ID 175862

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for python39:3.9 / python39-devel:3.9.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:2764 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.

The following packages have been upgraded to a later upstream version: python39 (3.9.16).

Security Fix(es):

* python: int() type in PyLong_FromString() does not limit amount of digits converting text to int leading to DoS (CVE-2020-10735)

* python: open redirection vulnerability in lib/http/server.py may lead to information disclosure (CVE-2021-28861)

* python: CPU denial of service via inefficient IDNA decoder (CVE-2022-45061)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Additional Changes:

For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.8 Release Notes linked from the References section.

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

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

Solution

Update the RHEL python39:3.9 / python39-devel:3.9 packages based on the guidance in RHSA-2023:2764.
