"This update for python36 fixes the following issues :

CVE-2019-18348: Fixed a CRLF injection via the host part of the url
passed to urlopen() (bsc#1155094)

CVE-2019-20916: Fixed a directory traversal in _download_http_url()
(bsc#1176262).

CVE-2020-27619: Fixed an issue where the CJK codec tests call eval()
on content retrieved via HTTP (bsc#1178009).

CVE-2020-8492: Fixed a regular expression in urrlib that was prone to
denial of service via HTTP (bsc#1162367).

Working-around missing python-packaging dependency in python-Sphinx is
not necessary anymore (bsc#1174571).

Build of python3 documentation is not independent on the version of
Sphinx(bsc#1179630).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
