  <impact type="high">
    <p>A local unprivileged user, by sending a specially crafted Polkit query,
      could possibly execute arbitrary code with the privileges of the process,
      escalate privileges or cause a Denial of Service condition.

  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All systemd users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=sys-apps/systemd-244.3"
