Examining data/wmcpu-1.4/wmcpu.c

FINAL RESULTS:

data/wmcpu-1.4/wmcpu.c:70:15:  [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 ((ch = getopt(argc, argv, "d:hvlt:")) != EOF) {
data/wmcpu-1.4/wmcpu.c:85:15:  [2] (integer) atol:
  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).
					udelay = atol(optarg);
data/wmcpu-1.4/wmcpu.c:111:2:  [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 str[128];
data/wmcpu-1.4/wmcpu.c:129:11:  [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).
	if((fp = fopen("/proc/meminfo", "r")) != NULL) {
data/wmcpu-1.4/wmcpu.c:176:12:  [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).
	if ((fp = fopen("/proc/stat", "r")) != NULL) {
data/wmcpu-1.4/wmcpu.c:210:12:  [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).
	if ((fp = fopen("/proc/loadavg", "r")) != NULL) {
data/wmcpu-1.4/wmcpu.c:253:27:  [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).
	if (has_meminfo && (fp = fopen("/proc/meminfo", "r")) != NULL) {
data/wmcpu-1.4/wmcpu.c:294:12:  [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).
	if ((fp = fopen("/proc/uptime", "r")) != NULL) {
data/wmcpu-1.4/wmcpu.c:140:9:  [1] (buffer) fscanf:
  It's unclear if the %s limit in the format string is small enough
  (CWE-120). Check that the limit is sufficiently small, or use a different
  input function.
		while(fscanf(fp," %127s%*[^\n]",str) > 0) {
data/wmcpu-1.4/wmcpu.c:178:3:  [1] (buffer) fscanf:
  It's unclear if the %s limit in the format string is small enough
  (CWE-120). Check that the limit is sufficiently small, or use a different
  input function.
		fscanf(fp, "%127s%f%f%f%f", str, info, info + 1, info + 2, info + 3);
data/wmcpu-1.4/wmcpu.c:337:2:  [1] (obsolete) usleep:
  This C routine is considered obsolete (as opposed to the shell command by
  the same name). The interaction of this function with SIGALRM and other
  timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is
  unspecified (CWE-676). Use nanosleep(2) or setitimer(2) instead.
	usleep(udelay);
