Buffer/Stack Overflow

This chapter explains basics of the stack, how to exploit the stack, and the workflow to achieve a buffer overflow. It's important to know that a new stack is created every time we run a function. The size of the stack frame is fixed after the creation using the prologue instructions, and the stack frame is deleted at the end of the function The chapter explains the concept of buffer overflow to exploit a remote server and get a remote shell. The chapter provides an example to see how the PUSH instruction works. The POP instruction is the opposite of the PUSH mechanism. The best way to understand how the stack works is through a real example. The C language is a great language to use when it comes to learning the assembly instructions. The vulnerable application we will use in this lab is dedicated to exploitation.
