The Shellcoder's Handbook

The black hats have kept up with security enhancements. Have you?
In the technological arena, three years is a lifetime. Since the first edition of this book was published in 2004, built-in security measures on compilers and operating systems have become commonplace, but are still far from perfect. Arbitrary-code execution vulnerabilities still allow attackers to run code of their choice on your system--with disastrous results.
In a nutshell, this book is about code and data and what happens when the two become confused. You'll work with the basic building blocks of security bugs--assembler, source code, the stack, the heap, and so on. You'll experiment, explore, and understand the systems you're running--and how to better protect them.
