MicrosoftWindows XP SP2 Heap protection


It was discovered by MaxPatrol team that it is possible to defeat MicrosoftR
WindowsR XP SP2 Heap protection and Data Execution Prevention mechanism.

As a result it is possible to implement:
- Arbitrary memory region write access (smaller or equal to 1016 bytes);
- Arbitrary code execution;
- DEP bypass.

Details are described in the article:
