Fedora 32: 2020-8bdd3fd7a4 Critical: Python 3.6 Header Injection DoS

Python 3.6 package for developers.

This package exists to allow developers to test their code against an older

version of Python. This is not a full Python stack and if you wish to run

your applications with Python 3.6, see other distributions

that support it, such as CentOS or RHEL with Software Collections

or older Fedora releases.

# 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.
