Details
It was discovered that Python incorrectly parsed certain email addresses. A
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
