"This update for python3 fixes the following issues :

CVE-2019-20907: Fixed denial of service by avoiding possible infinite
loop in specifically crafted tarball (bsc#1174091).

CVE-2020-14422: Fixed an improper computation of hash values in the
IPv4Interface and IPv6Interface could have led to denial of service
(bsc#1173274).

CVE-2019-16935: Fixed a reflected XSS in python/Lib/DocXMLRPCServer.py
(bsc#1153238).

CVE-2019-9947: Fixed an issue in urllib2 which allowed CRLF injection
if the attacker controls a url parameter (bsc#1130840).

If the locale is 'C', coerce it to C.UTF-8 (bsc#1162423).

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.");
