The Frame Pointer OverwriteAdded by Papergrl
Description:
Buffers can be overflowed, and by overwriting critical data stored in the target process's address space, we can modify its execution flow. This is old news. This article is not much about how to exploit buffer overflows, nor does it explain the vulnerability itself. It just demonstrates it is possible to exploit such a vulnerability even under the worst conditions, like when the target buffer can only be overflowed by one byte. Many other esoteric techniques where the goal is to exploit trusted processes in the most hostile situations exist, including when privileges are dropped. We will only cover the one byte overflow here.
