How to fix?

Upgrade Debian:9 python2.7 to version 2.7.13-2+deb9u4 or higher.

NVD Description

Note: Versions mentioned in the description apply to the upstream python2.7 package. See How to fix? for Debian:9 relevant versions.

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.
