CVE-2011-0411 Information

Description

The STARTTLS implementation in Postfix 2.4.x before 2.4.16 2.5.x before 2.5.12 2.6.x before 2.6.9 and 2.7.x before 2.7.3 does not properly restrict I/O buffering which allows man-in-the-middle attackers to insert commands into encrypted SMTP sessions by sending a cleartext command that is processed after TLS is in place related to a \plaintext command injection\ attack.
