Bug description:
  The pivot_root implementation in fs/namespace.c in the Linux kernel
  through 3.17 does not properly interact with certain locations of a
  chroot directory, which allows local users to cause a denial of
  service (mount-tree loop) via . (dot) values in both arguments to the
  pivot_root system call.
