Bug description:
  The rock_continue function in fs/isofs/rock.c in the Linux kernel
  through 3.18.1 does not restrict the number of Rock Ridge continuation
  entries, which allows local users to cause a denial of service
  (infinite loop, and system crash or hang) via a crafted iso9660 image.

  Break-Fix: - f54e18f1b831c92f6512d2eedb224cd63d607d3d
