RHEL 8 : python27:2.7 (RHSA-2020:1605)

critical Nessus Plugin ID 136044

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1605 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.

The following packages have been upgraded to a later upstream version: python2 (2.7.17). (BZ#1759944)

Security Fix(es):

* python-urllib3: Cross-host redirect does not remove Authorization header allow for credential exposure (CVE-2018-20060)

* python: Cookie domain check returns incorrect results (CVE-2018-20852)

* python-urllib3: CRLF injection due to not encoding the '\r\n' sequence leading to possible attack on internal service (CVE-2019-11236)

* python-urllib3: Certification mishandle when error should be thrown (CVE-2019-11324)

* python: email.utils.parseaddr wrongly parses email addresses (CVE-2019-16056)

* python-requests: Redirect from HTTPS to HTTP does not remove Authorization header (CVE-2018-18074)

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 8.2 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 affected packages.
