FINAL RESULTS:

data/wob-0.6/wob.c:428:14:  [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 ((c = getopt(argc, argv, "t:m:W:H:o:b:p:a:M:vh")) != -1) {
data/wob-0.6/wob.c:119:2:  [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 shm_name[3 * sizeof(unsigned int) + sizeof("wob-")] = {0};
data/wob-0.6/wob.c:121:3:  [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.
		sprintf(shm_name, "wob-%u", i);
data/wob-0.6/wob.c:378:3:  [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(destination, source, MIN(destination - source, end - destination) * sizeof(argb_color));
data/wob-0.6/wob.c:557:3:  [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 input_buffer[INPUT_BUFFER_LENGTH] = {0};
