Welcome finally, to a tutorial on buffer overflows! At last we have reached an exciting part of this series where I will dedicate the entire article on explaining and exploiting the notorious vulnerability. Grab some popcorn, sit back and enjoy the show.
Welcome back, my hacker novitiates! In the previous two posts in this series, we looked at the basics of buffer overflows. In this post, we will look at one technique for finding buffer overflows. We will try to send random, oversized, and invalid data at a variable to see whether we can make it crash or overflow. This process is known as fuzzing. It is often the first step to developing an exploit, as we need to find some variable that is susceptible to overflowing.
While our time with the Protostar VM from Exploit Exercises was lovely, we must move on to bigger things and harder challenges.

Before you start this recipe, make sure you have the proper pan: You'll need a 9- or 10-inch cake pan with sides that are at least 2 inches tall. (Most standard 9-inch cake pans have 1-inch sides, which will leave you with overflowing batter.) If you strike out in the cake pan department, an ovenproof skillet with similar dimensions will work. This cake is so fabulous, I would strongly consider buying a 9 by 2-inch cake pan especially for this recipe. It's surprisingly easy to make, and as a ...
