RHEL 8 : python27:2.7 (RHSA-2021:1761)

critical Nessus Plugin ID 149710

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for python27:2.7.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:1761 advisory.

Python is an interpreted, interactive, object-oriented programming language that supports modules, classes, exceptions, high-level dynamic data types, and dynamic typing. The python27 packages provide a stable release of Python 2.7 with a number of additional utilities and database connectors for MySQL and PostgreSQL.

Security Fix(es):

* python: CRLF injection via HTTP request method in httplib/http.client (CVE-2020-26116)

* python-urllib3: CRLF injection via HTTP request method (CVE-2020-26137)

* python-lxml: mXSS due to the use of improper parser (CVE-2020-27783)

* python: Stack-based buffer overflow in PyCArg_repr in _ctypes/callproc.c (CVE-2021-3177)

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 8.4 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 python27:2.7 package based on the guidance in RHSA-2021:1761.
