FINAL RESULTS:

data/haskell-network-3.1.1.1/cbits/ancilData.c:41:3:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
  char  buf[2];

data/haskell-network-3.1.1.1/cbits/winSockErr.c:70:5:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
