I have been working on finding an overflow in WordPad and I was able to run an exception with an undefined behavior (my point of view).
I am using x64dbg (I am not a pro x64dbg) and it shows unexpected HRESULT and almost all registers filled with random values (they don't get filled when a non-corrupted file is loaded).
I am new to x64dbg — how would I go saying this is vulnerable? How do I analyze the exception and the behavior? How do I exploit it?
I have so many questions. Please help. The memory dump is too big, so it is impossible to identify anything. What steps should I follow? Sometimes shows
unexpected HRESULT on R8 register as well.
