FINAL RESULTS:

data/haskell-attoparsec-0.13.2.4/examples/rfc2616.c:34:5:  [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 value[0];
data/haskell-attoparsec-0.13.2.4/examples/rfc2616.c:69:5:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
    memcpy(dst->value, src, len);
data/haskell-attoparsec-0.13.2.4/examples/rfc2616.c:84:5:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
    memcpy(p->value + (*dst)->len, src, len);
data/haskell-attoparsec-0.13.2.4/examples/rfc2616.c:206:2:  [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[HTTP_MAX_HEADER_SIZE];
data/haskell-attoparsec-0.13.2.4/examples/rfc2616.c:228:7:  [2] (misc) open:
  Check when opening files - can an attacker redirect it (via symlinks),
  force the opening of special file type (e.g., device files), move things
  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
	fd = open(argv[i], O_RDONLY);
data/haskell-attoparsec-0.13.2.4/examples/rfc2616.c:209:10:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	nread = read(fd, buf, sizeof(buf));
