      privileges or a Denial of Service condition.

  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All Logwatch users should upgrade to the latest version:</p>

      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=sys-apps/logwatch-7.4.0"
    </code>
