FINAL RESULTS:

data/clthreads-2.4.2/source/a_thread.cc:47:8:  [4] (format) vprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
    M->vprintf (fmt, ap);
data/clthreads-2.4.2/source/clthreads.h:685:10:  [4] (format) vprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
    void vprintf (const char *fmt, va_list ap);
data/clthreads-2.4.2/source/clthreads.h:686:10:  [4] (format) printf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
    void printf (const char *fmt, ...);
data/clthreads-2.4.2/source/textmsg.cc:42:15:  [4] (format) vprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
void Textmsg::vprintf (const char *fmt, va_list ap)
data/clthreads-2.4.2/source/textmsg.cc:44:16:  [4] (format) vsnprintf:
  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.
    _strlen += vsnprintf (_text + _strlen, _size - _strlen, fmt, ap);
data/clthreads-2.4.2/source/textmsg.cc:49:15:  [4] (format) printf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
void Textmsg::printf (const char *fmt, ...)
data/clthreads-2.4.2/source/textmsg.cc:54:5:  [4] (format) vprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
    vprintf (fmt, ap);
data/clthreads-2.4.2/source/a_thread.cc:37:21:  [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 (*p) _inst = atoi (p);
data/clthreads-2.4.2/source/clthreads.h:651:5:  [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    _name [32];
data/clthreads-2.4.2/source/a_thread.cc:34:5:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
    strncpy (_name, name, 32);
data/clthreads-2.4.2/source/clthreads.h:675:12:  [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).
    size_t strlen (void) const { return _strlen; }
