      the running environment of untrusted applications using Linux namespaces
      and seccomp-bpf.

  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>

      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=sys-apps/firejail-0.9.44.8"
    </code>
    
    <p>All Firejail-lts users should upgrade to the latest version:</p>
