chapters/mitigations-and-defensive-strategies: Add Dockerfile for 02-rwslotmachine2

[gabrielmocanu]

Description:

Create a Dockerfile for 02-rwslotmachine2 exercise.

Requirements:

1. Use a multi-stage Dockerfile:

• Build Stage:
  - Compile the provided C code into an executable.
• Runtime Stage:
  - Run the compiled executable and ensure it listens or operates on port 31345.

2. Verify the functionality of the solution to ensure that it works as expected after building and running the Dockerfile.

3. Ensure the Dockerfile is optimized and avoids unnecessary layers.

Expected Outcome:

A fully working Dockerfile that can be built and executed in two separate stages, satisfying the above requirements.

Hi, @gabrielmocanu! I am eager to take care of this issue. I am already on to it, I have managed to create the Dockerfile environment by now, but I am still working on the solution, I still need to find the flag. I have noticed there is a problem with the overwrite functions and I assume it is because of the addresses, but I will take a deeper look.
