  <impact type="normal">
    <p>A remote attacker could entice a user to run a program where attacker
      controls the output inside a rxvt terminal window, possibly resulting in
      execution of arbitrary code with the privileges of the process or a
      Denial of Service condition.

    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All rxvt-unicode users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=x11-terms/rxvt-unicode-9.22-r9"
