Advisory Release Date: 2019-10-30 20:47 Pacific

References: CVE-2019-16056 

Issue Overview:

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 )
