  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted file,
    using excessive CPU ressources and possibly leading to a Denial of
    Service. Note that this vulnerability could be also triggered through
    an automatic file scanner like amavisd-new.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All file users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=sys-apps/file-4.20-r1&quot;</code>
  </resolution>
