New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 3.6

Synopsis

The remote Fedora host is missing a security update.

Description

# Python 3.6.11

Python 3.6.11 is the latest security fix release of Python 3.6.

- bpo-39073: Disallow CR or LF in email.headerregistry.Address arguments to guard against header injection attacks.

- bpo-38576: Disallow control characters in hostnames in http.client, addressing CVE-2019-18348. Such potentially malicious header injection URLs now cause a InvalidURL to be raised.

- bpo-39503: CVE-2020-8492: The AbstractBasicAuthHandler class of the urllib.request module uses an inefficient regular expression which can be exploited by an attacker to cause a denial of service. Fix the regex to prevent the catastrophic backtracking. Vulnerability reported by Ben Caller and Matt Schwager.

Also fix a regression with `distutils.sysconfig.get_config_var('LIBPL')` value in Fedora specific patches.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python36 package.
