FINAL RESULTS:

data/idle3-tools-0.9.1/idle3ctl.c:139:3:  [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 buffer[512];

  char buffer[512];
data/idle3-tools-0.9.1/idle3ctl.c:313:36:  [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).
      if (strlen(argv[i])>2) timer=atoi(argv[i]+2);
data/idle3-tools-0.9.1/idle3ctl.c:315:29:  [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).
        if (++i<argc) timer=atoi(argv[i]);
data/idle3-tools-0.9.1/idle3ctl.c:332:12:  [2] (misc) open:
  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).
      fd = open(device, O_RDONLY|O_NONBLOCK);
data/idle3-tools-0.9.1/sgio.c:161:11:  [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.

	unsigned char sb[32], *desc;
data/idle3-tools-0.9.1/idle3ctl.c:313:11:  [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).
