FINAL RESULTS:

data/jkmeter-0.8.0/source/mainwin.cc:156:2:  [4] (format) sprintf:
  Potential format string problem (CWE-134). Make format string constant.
	sprintf (s, (p < -9.9f) ? "%3.0lf" : "%3.1lf", p);
data/jkmeter-0.8.0/source/mainwin.cc:290:5:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
    sprintf (s, "%s   %s-%s", _jclient->jname (), PROGNAME, VERSION);
data/jkmeter-0.8.0/source/cmeter.cc:116:5:  [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 s [1024];
data/jkmeter-0.8.0/source/jclient.cc:50:5:  [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           t [16];
data/jkmeter-0.8.0/source/jclient.cc:75:2:  [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 (t, "in-%d", i + 1);
data/jkmeter-0.8.0/source/kmeter.cc:250:5:  [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     s [1024];
data/jkmeter-0.8.0/source/mainwin.cc:48:9:  [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).
    r = atoi (p);
data/jkmeter-0.8.0/source/mainwin.cc:150:5:  [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  s [16];
data/jkmeter-0.8.0/source/mainwin.cc:221:5:  [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        s [1024];
data/jkmeter-0.8.0/source/png2img.cc:38:9:  [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).
    F = fopen (file, "r");
data/jkmeter-0.8.0/source/kmeterdsp.cc:118:17:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
void Kmeterdsp::read (float *rms, float *dpk)
data/jkmeter-0.8.0/source/kmeterdsp.h:33:10:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    void read (float *rms, float *dpk);
data/jkmeter-0.8.0/source/mainwin.cc:110:54:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    if (_corr) _cmeter->update (_jclient->scdsp ()-> read ());
data/jkmeter-0.8.0/source/mainwin.cc:141:26:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    _jclient->kmdsp (k)->read (&r, &p);
data/jkmeter-0.8.0/source/stcorrdsp.cc:76:18:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
float Stcorrdsp::read (void)
data/jkmeter-0.8.0/source/stcorrdsp.h:33:11:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    float read (void);
