This is a proof of concept exploit that allows an attacker to execute arbitrary code via vectors involving a dereferenced memory address in Microsoft Internet Explorer 8. It leverages the issue discussed in MS11-081. The exploit is slightly crippled by the author.
31cef28f3ae91f47c652ada6f2b786f3ba4d464050c6d2c3cfd46b5a0f99df82Zero Day Initiative Advisory 11-288 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer 8. 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 how the application verifies arguments for a certain operation performed on an element. When parsing one of the operands of a method, the application will pass the argument straight to a method that will use the variant as an index. Due to bypassing the argument check, an aggressor can set the index to point to data outside the bounds of the array. This can lead to code execution under the context of the application.

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.
