* python: CRLF injection via the path part of the url passed to urlopen() (CVE-2019-9947)

* python: Undocumented local_file protocol allows remote attackers to bypass protection mechanisms (CVE-2019-9948)

* python-urllib3: CRLF injection due to not encoding the '\r\n' sequence leading to possible attack on internal service (CVE-2019-11236)

* python-urllib3: Certification mishandle when error should be thrown (CVE-2019-11324)
