705288: CVE-2011-1926 cyrus-imapd: STARTTLS plaintext command injection

The MITRE CVE dictionary describes this issue as:

The STARTTLS implementation in Cyrus IMAP Server before 2.4.7 does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted sessions by sending a cleartext command that is processed after TLS is in place, related to a "plaintext command injection" attack, a similar issue to CVE-2011-0411.
