Descripción
La implementación STARTTLS en Cyrus IMAP Server anterior a v2.4.7 no restringe adecuadamente el búfer de Entrada/Salida, lo que permite ataques "man-in-the-middle" para insertar comandos en sesiones cifradas enviando un comando en texto claro que se procesa después de TLS en su lugar, relacionado con un ataque "inyección de comandos de texto claro", una tarea similar a CVE-2011-0411.
