Descriptions

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.

La implementación de STARTTLS de Postfix 2.4.x anteriores a 2.4.16, 2.5.x anteriores a 2.5.12, 2.6.x anteriores a 2.6.9, y 2.7.x anteriores a 2.7.3 no restringe apropiadamente el buffering de I/O, lo que permite a atacantes man-in-the-middle insertar comandos en sesiones SMTP encriptadas enviando un comando en texto claro que es procesado después de que TLS es iniciado. Relacionado con un ataque de "inyección de comandos de texto en claro".
