Introduction
In Chapter 7 we introduced several different generic approaches and techniques you can use when dealing with the challenges inherent in remote exploitation. In this chapter, we will analyze real code used to exploit remote kernel heap memory corruption affecting the Linux kernel SCTP network stack. We chose to work with this particular vulnerability for the following reasons:
-
Linux source code is freely available, which makes for an easier-to-follow discussion ...
