Lab 1: Program Security Lab
This lab will be completed on our Linux CSE servers (i.e., cse01 – cse06).
bufOvfl.c was written that contains a function called privateFunction() whose only purpose is to print out a congratulatory message and display a secret code word.

Without this compile option, our buffer overflow attack would result in the following error, even though done correctly:
