Bug description:
  Race condition in the handle_to_path function in fs/fhandle.c in the
  Linux kernel through 3.19.1 allows local users to bypass intended size
  restrictions and trigger read operations on additional memory
  locations by changing the handle_bytes value of a file handle during
  the execution of this function.
