(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."
