FINAL RESULTS:

data/libmurmurhash-1.5/test/mmh.c:93:2:  [4] (format) fprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
	fprintf(exit_code == EXIT_SUCCESS ? stdout : stderr, str);

data/libmurmurhash-1.5/test/mmh.c:26:16:  [3] (buffer) getopt:
  Some older implementations do not protect against internal buffer overflows
  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
	while ((opt = getopt(argc, argv, "h")) != -1) {

data/libmurmurhash-1.5/murmurhash.c:17:3:  [2] (buffer) memcpy:

data/libmurmurhash-1.5/murmurhash.c:45:11:  [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.
	unsigned char data[sizeof(uint32_t)];

data/libmurmurhash-1.5/test/mmh.c:43:11:  [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).
	int fd = open(file_name, O_RDONLY);
