Microsoft Windows Kernel - 'HmgAllocateObjectAttr' Use-After-Free (MS15-061)

Source: https://code.google.com/p/google-security-research/issues/detail?id=320

The PoC bug checks reliably with Special Pool enabled on writing to freed memory. A reference to the freed memory is held at offset +0x10 of the THREADINFO object. This memory is referenced in HmgAllocateObjectAttr which is called in multiple locations. The freed memory is a struct inside a Brush Object which is freed in the call NtGdiDeleteObjectApp.
