Because of the vulnerability (see notes at the end of the module) DEP bypass has not been achieved.
The derefence is done against a buffer on the heap as base, and user controlled parameter as offset. The buffer on the heap is allocated along the activex initialization, and doesn't use the default heap. Because of this achieving heap feng shui doesn't seem easy. As we added a module for cve-2012-0266 too (see #812) I've added it anyway for CVE coverage. And it's an interesting vuln anyway :)
