Bug description:
When aufs module is loaded with "modprobe aufs allow_userns",
unprivileged user can use xattrs on the working directory or aufs
mount over a fuse mount to create SUID/SGID binaries, thus escalating
privileges. These errors are quite similar to those on overlayfs:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1535150
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1534961
aufs developers have already confirmed and issued a fix:
https://sourceforge.net/p/aufs/mailman/message/34864744/
