USN-4151-1 fixed several vulnerabilities in Python. This update provides
the corresponding update for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM.

remote attacker could possibly use this issue to trick Python applications
into accepting email addresses that should be denied. (CVE-2019-16056)

It was discovered that the Python documentation XML-RPC server incorrectly
handled certain fields. A remote attacker could use this issue to execute a
