Synopsis

The remote SUSE host is missing one or more security updates.

Description

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.
