FINAL RESULTS:

data/libmirisdr-0.0.4.59ba37/src/miri_sdr.c:116:16:  [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, "d:f:g:s:b:S::")) != -1) {
data/libmirisdr-0.0.4.59ba37/src/libmirisdr.c:309:4:  [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(gains, msi001_gains, len);
data/libmirisdr-0.0.4.59ba37/src/miri_sdr.c:110:2:  [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 vendor[256] = { 0 }, product[256] = { 0 }, serial[256] = { 0 };
data/libmirisdr-0.0.4.59ba37/src/miri_sdr.c:119:16:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
			dev_index = atoi(optarg);
data/libmirisdr-0.0.4.59ba37/src/miri_sdr.c:150:14:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
	dev_index = atoi(argv[1]);
data/libmirisdr-0.0.4.59ba37/src/miri_sdr.c:151:14:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
	samp_rate = atoi(argv[2])*1000;
data/libmirisdr-0.0.4.59ba37/src/miri_sdr.c:153:14:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
	frequency = atoi(argv[4]);
data/libmirisdr-0.0.4.59ba37/src/miri_sdr.c:253:10:  [2] (misc) fopen:
  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).
		file = fopen(filename, "wb");
