Plaintext injection in STARTTLS (multiple implementations)

This is a writeup about a flaw that I found recently, and that existed in multiple implementations of SMTP Simple Mail Transfer Protocol over TLS Transport Layer Security including my Postfix open source mailserver. I give an overview of the problem and its impact, how to find out if a server is...
