Bug description:
  Integer overflow in the LZ4 algorithm implementation, as used in Yann
  Collet LZ4 before r118 and in the lz4_uncompress function in
  lib/lz4/lz4_decompress.c in the Linux kernel before 3.15.2, on 32-bit
  platforms might allow context-dependent attackers to cause a denial of
  service (memory corruption) or possibly have unspecified other impact
  via a crafted Literal Run that would be improperly handled by programs
  not complying with an API limitation, a different vulnerability than
  CVE-2014-4715.

  Break-Fix: cffb78b0e0b3a30b059b27a1d97500cf6464efa9
  206204a1162b995e2185275167b22468c00d6b36
