SELinux implementation with virtual machines

[nengo]

I am working with SELinux for my final year project.My objective is to show how to prevent zero day exploits with SELinux.I am planning to use virtual machines for the project.
At the moment i am still learning SELinux.
My problem is how to obtain the necessary programs eg vulnerable daemons that i can use to demonstrate how SELinux solves zero day exploits.
I still haven't managed to set up the virtual machines, i will appreciate if someone could explain to me how to go about it.

well, you can do what lots of scriptkiddies do.
First find a exploit, and then find what you want to attack.
milw0rm - exploits : vulnerabilities : videos : papers : shellcode has a nice exploits database.
it might be good to show that exploit from snort 2.6 (Im not sure if that numbr is correct) since snort is a IDS it self its terible if it gets exploited.
