You have been provided the following files: "vul.c".
The goal is to change the value of variable "var" (found in file vul.c) to 0xCCAFEF64 while using the "%hhn" format specifier as opposed to using the "%hn" format specifier, which the book and slides have already solved.
For the input you will be using the method which is utilizing the "echo" command along with the "$()" command to provide the correct input to the “vul” binary (or any name you chose to save your binary as).
Note: the address for "var" will probably be different on your machine.
In Summary:
-----------------
1- Show me the input in the following format:
echo $(printf .....fill in your answers here....... > input
2- Show me the screenshot of the actual output and explanation for each point. (Each screenshot has to have the attached wallpaper [[login to view URL]])
3- Explain your answer
