"An issue was discovered in Python through 2.7.16, 3.x through 3.5.7,
3.6.x through 3.6.9, and 3.7.x through 3.7.4. The email module wrongly
parses email addresses that contain multiple @ characters. An
application that uses the email module and implements some kind of
checks on the From/To headers of a message could be tricked into
accepting an email address that should be denied. An attack may be the
same as in CVE-2019-11340 ; however, this CVE applies to Python more
generally. (CVE-2019-16056)");
