    It was discovered that the STARTTLS implementation of the Cyrus IMAP 
    server does not properly restrict I/O buffering, which allows 
    man-in-the-middle attackers to insert commands into encrypted IMAP, 
    LMTP, NNTP and POP3 sessions by sending a cleartext command that is 
    processed after TLS is in place.
    
    For the oldstable distribution (lenny), this problem has been fixed in
    version 2.2.13-14+lenny4.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 2.2.13-19+squeeze1.
