    (Mailutils: Multiple vulnerabilities in imap4d and mail)
    
        infamous41d discovered several vulnerabilities in GNU Mailutils.
        imap4d does not correctly implement formatted printing of command tags
        (CAN-2005-1523), fails to validate the range sequence of the 'FETCH'
        command (CAN-2005-1522), and contains an integer overflow in the
        'fetch_io' routine (CAN-2005-1521). mail contains a buffer overflow in
        'header_get_field_name()' (CAN-2005-1520).
      
    Impact :
    
        A remote attacker can exploit the format string and integer
        overflow in imap4d to execute arbitrary code as the imap4d user, which
        is usually root. By sending a specially crafted email message, a remote
        attacker could exploit the buffer overflow in the 'mail' utility to
        execute arbitrary code with the rights of the user running mail.
        Finally, a remote attacker can also trigger a Denial of Service by
        sending a malicious FETCH command to an affected imap4d, causing
        excessive resource consumption.
      
    Workaround :
    
        There are no known workarounds at this time."
