        I totally get the cool solution for the CTF but what practical application does the bug report solve? The only one I can think of is where a private registry scanner requires Ubuntu and the image scan passes. I can create a base image with any security holes I want. (1/2)

        The same situation could be created with a malicious Ubuntu install on a VM. Or on bare metal with SAN Storage. It is an Ubuntu problem. And requires insider access or running VMs or Container images blindly.
