Bug description:
  The clone system-call implementation in the Linux kernel before 3.8.3
  does not properly handle a combination of the CLONE_NEWUSER and
  CLONE_FS flags, which allows local users to gain privileges by calling
  chroot and leveraging the sharing of the / directory between a parent
  process and a child process.

  Break-Fix: 5eaf563e53294d6696e651466697eb9d491f3946
  e66eded8309ebf679d3d3c1f5820d1f2ca332c71
