Description

Windows Kernel - NtGdiStretchBlt Pool Buffer Overflows (MS15-097). CVE-2015-2512. Dos exploit for win32 platform

                                        
                                            Source: https://code.google.com/p/google-security-research/issues/detail?id=415

Tested on Win 7 32-bit with Special Pool enabled. 

Multiple pool buffer overflows can be triggered through the NtGdiStretchBlt system call. The attached PoC demonstrates a write overflow and another read over flow issue which is likely to be usable for memory leaks (enabled by uncommenting the first NtGdiStretchBlt call).
