Name of the Vulnerable Software and Affected Versions
Python versions prior to 2.7.12
Python 3.x versions prior to 3.4.5
Python 3.5.x versions prior to 3.5.2
Description
The issue allows man-in-the-middle attackers to bypass TLS protections by blocking the StartTLS command, also known as a "StartTLS stripping attack." This occurs because the smtplib library in Python does not return an error when StartTLS fails.
Recommendations
For Python versions prior to 2.7.12, update to version 2.7.12 or later.
For Python 3.x versions prior to 3.4.5, update to version 3.4.5 or later.
For Python 3.5.x versions prior to 3.5.2, update to version 3.5.2 or later.
