ASLR

The goal of this lab is to implement a minimal ASLR for Minix.

The lab consists of three tasks:

• Demonstrate that the program in /usr/games/overflow has a vulnerability due to a buffer overflow
• Modify Minix (Kernel, user lib, services, etc) to randomize position of stack and heap of processes. Each process should be randomized differently.
• Demonstrate that ASLR counters the attack

Submission consists of

• A commit of your repository. Tag the commit the "Exercise v.1"
• If you resubmit your solution, tag the new commit with "Exercise v.x"

If your project target a different open source software you must agree with Roberto for a different assignment. The goal of the assignment is to demonstrate that you can navigate the code of the project and apply some modifications.
