      objects and functions.
    </p>

  <description>
    <p>When libdbus is used in a setuid program, a user can gain escalated
      privileges by leveraging the DBUS_SYSTEM_BUS_ADDRESS variable. GLib can
      be used in a setuid context with D-Bus, and so can trigger this
      vulnerability. Please review the CVE identifier below for more details.
    </p>

  <impact type="high">

    </p>
  </impact>
  <workaround>
