Exploitation of Use - After - Free Modules

In this post we will be discussing how to exploit a Use - After - Free bug in both UseAfterFreeExecModule and UseAfterFreeWriteModule.

To that end, in UseAfterFreeExecModule we will be able to control a function pointer, whereas in UseAfterFreeWriteModule we are given a Write - What - Where condition.
