Morello protects a vulnerable program to run malicious code

[josephproject1]

1. In this program, the program reads 300 bytes of data from a file called "riskfile" an then copies, the data to a buffer of size 100
2. Clearly there is a buffer overflow in the program
3. The program tries contents copies to a buffer come from a user-provided file and users including malicious can control what is copied to the buffer
4. The question is what to store in "riskfile"? So after overflowing the buffer, we can get the program run our code
5. Morello protects this vulnerable program after identifying this vulnerability
