Smashing The Kernel Stack

This article written by Sinan "noir" Eren is about recent exposures of many kernel level vulnerabilities and advances in their exploitation which leads to trusted (oops safe) and robust exploits. It focuses on 2 recent vulnerabilities in the OpenBSD kernel. The goal of this paper is to explore and demonstrate generic ways to exploit stack overflows and signed/unsigned vulnerabilities in kernel space.
