Examining data/stress-1.0.4/src/stress.c

FINAL RESULTS:

data/stress-1.0.4/src/stress.c:43:3:  [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(OUT, STR, ##ARGS), fflush(OUT)
data/stress-1.0.4/src/stress.c:47:3:  [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(OUT, STR, ##ARGS), fflush(OUT)
data/stress-1.0.4/src/stress.c:51:3:  [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(OUT, STR, ##ARGS), fflush(OUT)
data/stress-1.0.4/src/stress.c:55:3:  [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(OUT, STR, ##ARGS), fflush(OUT)
data/stress-1.0.4/src/stress.c:726:3:  [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 (stdout, mesg, global_progname, VERSION);
data/stress-1.0.4/src/stress.c:759:3:  [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 (stdout, mesg, global_progname, global_progname, global_progname);
data/stress-1.0.4/src/stress.c:543:3:  [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 buff[chunk];
data/stress-1.0.4/src/stress.c:561:17:  [2] (tmpfile) mkstemp:
  Potential for temporary file vulnerability in some circumstances. Some
  older Unix-like systems create temp files with permission to write by all
  by default, so be sure to set the umask to override this. Also, some older
  Unix systems might fail to use O_EXCL when opening the file, so make sure
  that O_EXCL is used by the library (CWE-377).
      if ((fd = mkstemp (name)) == -1)
data/stress-1.0.4/src/stress.c:299:15:  [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 (backoff);
data/stress-1.0.4/src/stress.c:320:15:  [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 (backoff);
data/stress-1.0.4/src/stress.c:340:15:  [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 (backoff);
data/stress-1.0.4/src/stress.c:361:15:  [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 (backoff);
data/stress-1.0.4/src/stress.c:620:14:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
  if ((pos = strlen (nptr) - 1) < 0)
data/stress-1.0.4/src/stress.c:674:14:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
  if ((pos = strlen (nptr) - 1) < 0)
