stealth/troubleshooter: Abstract: This paper demonstrates vulnerabilities within the SELinux framework as well as shortcomings in the type enforcement setup. I will show how to deconstruct a SELinux setup with some simple 80’s style exploit techniques. While reading this paper, I recommend listening to this music from the year of morrisworm.

When in 2012 the SELinux developers analyzed the behaivior of an exploit that was not designed to run on a SELinux system at page 32 of these slides – it triggered a review-selector for SELinux and I put it to the list of my audit targets. Not surprisingly, GingerBreak lost that “competition”, just because it was not made for it. Using my QUANTUM AUDIT techniques I was now able to have a deeper look into SELinux itself to see whether the claims that were made really hold.
