MSIE 9 IEFRAME CMarkup..RemovePointerPos use-after-free  
=======================================================  
(MS13-055, CVE-2013-3143)  
  
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, though their  
advisory (at http://www.zerodayinitiative.com/advisories/ZDI-13-163/)  
mentions an iframe, which is not in the repro I provided.  
  
Time-line  
---------  
* Sometime in November 2012: This vulnerability was found through fuzzing.  
* 11 November 2012: This vulnerability was submitted to EIP.  
* 10 December 2012: This vulnerability was rejected by EIP.  
* 12 December 2012: This vulnerability was submitted to ZDI.  
* 25 January 2013: This vulnerability was acquired by ZDI.  
* 15 February 2013: This vulnerability was disclosed to Microsoft by  
ZDI.  
* 26 July 2013: This vulnerability was address by Microsoft in MS13-055.  
* 14 December 2016: Details of this vulnerability are released.
