Synopsis

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

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:4273 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: python27-python (2.7.18).
(BZ#1882656)

Security Fix(es):

* python: CRLF injection via the host part of the url passed to urlopen() (CVE-2019-18348)

* python: infinite loop in the tarfile module via crafted TAR archive (CVE-2019-20907)

* python-pip: directory traversal in _download_http_url() function in src/pip/_internal/download.py (CVE-2019-20916)

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

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.

Bug Fix(es):

* python27-python-pip: Bundles own CA bundle instead of using system CA bundle (BZ#1882668)

* python27-python-pip: Contains multiple bundled libraries, and has no bundled() provides (BZ#1882669)

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