CVE: CVE-2018-20060,
     CVE-2019-11236,
     CVE-2019-11324

It was discovered that urllib3 incorrectly removed Authorization HTTP
headers when handled cross-origin redirects. This could result in
credentials being sent to unintended hosts (CVE-2018-20060).

injection (CVE-2019-11236).

The python-urllib3 package has been updated to version 1.24.3 to fix these
issues and other bugs.  The python-requests package has been fixed to work
