Bug description:
  The raw_cmd_copyout function in drivers/block/floppy.c in the Linux
  kernel through 3.14.3 does not properly restrict access to certain
  pointers during processing of an FDRAWCMD ioctl call, which allows
  local users to obtain sensitive information from kernel heap memory by
  leveraging write access to a /dev/fd device.

  Break-Fix: - 2145e15e0557a01b9195d1c7199a1b92cb9be81f
