FINAL RESULTS:

data/iec16022-0.2.4/image.c:365:4:  [4] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused).
			strcpy(buf + n, comment);
data/iec16022-0.2.4/iec16022.c:146:13:  [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 *f = fopen(infile, "rb");
data/iec16022-0.2.4/iec16022.c:164:7:  [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).
		W = atoi(size);
data/iec16022-0.2.4/iec16022.c:166:8:  [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).

data/iec16022-0.2.4/iec16022.c:171:9:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range

  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).

data/iec16022-0.2.4/iec16022.c:346:4:  [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 temp[74], c;
data/iec16022-0.2.4/iec16022.c:357:4:  [2] (buffer) memcpy:

data/iec16022-0.2.4/iec16022.c:360:16:  [2] (integer) atoi:

  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).

  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
