  <impact type="normal">
    <p>A remote attacker, pretending to be the E17 window manager, could
      possibly trigger an out-of-boundary heap write in feh while receiving an
      IPC message.  This could result 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>
  </workaround>
  <resolution>
    <p>All feh users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=media-gfx/feh-2.18.3"
    </code>
