This means that while 64 bytes of memory is allocated in the stack frame for the variable "buffer," there is nothing stopping us from passing more than 64 bytes into the variable. Just like in the last tutorial, Protostar will not let us write any information in the same directory as the stack5 program, so we need to move to a directory where we can write a new file. The first line tells the bash shell that we are writing a program that is to be run with the Python interpreter.

Lines 2 and 3 import packages that we will need while we create our exploit.

When you first run a program, all of the information that the program needs to execute is loaded into the RAM of the computer.

Once a program is loaded into this memory to run, it has five parts: Since we'll be taking a look at a stack overflow vulnerability, it makes sense to take some time to understand the stack.

Each function has its own stack frame which contains the local variables for that function, the parameters passed to the function when it was called, and most importantly, a return address which specifies what instruction the program should execute next once the function is done.

This organization results in what is referred to as a LIFO data structure.

LIFO stands for "last in first out" meaning that the last stack frame added to the stack is the first one which will be removed.

Each time a new function is called, a new stack frame is added on the top of the stack.

Likewise, each time a function finishes execution, it is removed from the stack.
