      archive using KDE Ark, possibly resulting in execution of arbitrary code
      with the privileges of the process or a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>

      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=kde-apps/ark-20.04.3-r2"
    </code>
