  <title>Mailutils: Multiple vulnerabilities in imap4d and mail</title>
  <synopsis>

    vulnerabilities, potentially allowing a remote attacker to execute
    arbitrary code with root privileges.

    <p>
    GNU Mailutils is a collection of mail-related utilities, including
    an IMAP4 server (imap4d) and a Mail User Agent (mail).

  <description>
    <p>
    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).
    </p>
  </description>
  <impact type="high">
    <p>
    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.
    </p>
  </impact>
  <workaround>
    <p>
    There are no known workarounds at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All GNU Mailutils users should upgrade to the latest available
    version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-mail/mailutils-0.6-r1"</code>
  </resolution>
