This Metasploit module exploits a vulnerability in Microsoft Internet Explorer. A memory corruption may occur when the Option cache isn't updated properly, which allows other JavaScript methods to access a deleted Option element, and results in code execution under the context of the user.
307b7adfa8d05c300b48db94ceb041a3ced231d646f14a788423d6874081b7c4Zero Day Initiative Advisory 11-287 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the caching implementation of a Select element. When modifying this cache, there are certain methods that do not update the cache correctly. Due to these inconsistencies, one can desynchronize the cache with elements that have been freed. While using these freed elements, the application's perception of type-safety becomes skewed and usage of the object can lead to code execution under the context of the application.
fdaefb0d3ef4ba650c4eed49e97330766ec02cd5c66f50e4795ac2130cfd44b9Two code execution vulnerabilities have been discovered in Internet Explorer. One vulnerability is caused by incorrectly validating integer parameter passed to the 'add' method of the Select HTML element. Another vulnerability is caused by a use-after-free bug triggered by accessing a previously deleted Option element.
