FINAL RESULTS:

data/python-pyalsa-1.1.6/pyalsa/alsaseq.c:30:28:  [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.
#define ddebug(x, args...) fprintf(stderr, x "\n",##args);
data/python-pyalsa-1.1.6/pyalsa/alsahcontrol.c:1186:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
		memcpy(iec958->status, str, len);
data/python-pyalsa-1.1.6/pyalsa/alsahcontrol.c:1194:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
		memcpy(iec958->subcode, str, len);
data/python-pyalsa-1.1.6/pyalsa/alsahcontrol.c:1202:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
		memcpy(iec958->dig_subframe, str, len);
data/python-pyalsa-1.1.6/pyalsa/alsaseq.c:673:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
  memcpy(self->event, event, sizeof(snd_seq_event_t));
data/python-pyalsa-1.1.6/pyalsa/alsaseq.c:680:5:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
    memcpy(self->buff, self->event->data.ext.ptr, self->event->data.ext.len);
data/python-pyalsa-1.1.6/pyalsa/alsaseq.c:2052:3:  [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 tmpclientname[1024];
data/python-pyalsa-1.1.6/pyalsa/alsaseq.c:2069:5:  [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(tmpclientname, "pyalsa-%d", getpid());
