MSIE 9 IEFRAME CView::EnsureSize use-after-free  
===============================================  
(MS13-021, CVE-2013-0090)  
  
Synopsis  
--------  
A specially crafted web-page can trigger a use-after-free vulnerability  
in Microsoft Internet Explorer 9. I did not investigate this  
vulnerability thoroughly, so I cannot speculate on the potential impact  
or exploitability.  
  
Known affected software and attack vectors  
------------------------------------------  
* Microsoft Internet Explorer 9  
  
An attacker would need to get a target user to open a specially  
crafted web-page. Disabling JavaScript should prevent an attacker  
from triggering the vulnerable code path.  
  
Details  
-------  
This bug was found back when I had very little knowledge and tools to do  
analysis on use-after-free bugs, so I have no details to share. ZDI  
revealed that this was a use-after-free vulnerability in their advisory  
at http://www.zerodayinitiative.com/advisories/ZDI-13-097/.
