FINAL RESULTS:

data/rem-0.6.0/src/aufile/aufile.c:127:10:  [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).
	af->f = fopen(filename, mode == AUFILE_READ ? "rb" : "wb");
data/rem-0.6.0/src/aumix/aumix.c:159:4:  [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(mix_frame, base_frame, mix->frame_size*2);
data/rem-0.6.0/src/dtmf/dec.c:23:14:  [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.
static const char keyv[4][4] = {{'1', '2', '3', 'A'},
data/rem-0.6.0/src/vid/frame.c:271:4:  [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(dd0, ds0, w);
data/rem-0.6.0/src/vid/frame.c:275:4:  [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(dd0, ds0, w);
data/rem-0.6.0/src/vid/frame.c:279:4:  [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(dd1, ds1, w/2);
data/rem-0.6.0/src/vid/frame.c:283:4:  [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(dd2, ds2, w/2);
data/rem-0.6.0/src/vid/frame.c:307:4:  [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(dd0, ds0, w);
data/rem-0.6.0/src/vid/frame.c:312:4:  [2] (buffer) memcpy:

			memcpy(dd2, ds2, w);
data/rem-0.6.0/src/vid/frame.c:339:4:  [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(dd0, ds0, w);
data/rem-0.6.0/src/vid/frame.c:343:4:  [2] (buffer) memcpy:

			memcpy(dd1, ds1, w);
data/rem-0.6.0/src/aumix/aumix.c:114:10:  [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.

  timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is
