Neither of these exploits works on stock Ubuntu 12.04 LTS, with LXC or otherwise (AppArmor kicks in).
Like jpetazzo, I would love to see a working LXC exploit. In my case, "working" == "can get host root when given container root on Ubuntu 12.04 or later".
The fact is that by the time you know about the "working" exploit it's already been fixed. Unless you're security-related researchers / engineers you're not very likely to get hold of a 0-day exploit.
