Just a very simple question with a very simple answer

I think a heap overflow is also a buffer overflow. According to http://stackoverflow.com/questions/1120575/what-is-the-difference-between-a-stack-overflow-and-buffer-overflow, a buffer overflow refers to any case in which a program writes beyond the end of the memory allocated for any buffer (including on the heap, not just on the stack). For example, if you write past the end of an array allocated from the heap, you’ve caused a buffer overflow. So the answer to your question would be yes as a heap overflow is a buffer overflow.

@YotM0DSeeker you are right, I made a mistake. With simple buffer overflow I was meaning stack overflow.

If you understand well what the difference between the stack and the buffer and how they work both, you’ll know as well how to exploit it ;
