FINAL RESULTS:

data/mpegdemux-0.1.4/src/message.c:48:3:  [4] (format) vfprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
		vfprintf (stderr, msg, va);
data/mpegdemux-0.1.4/src/mpegdemux.c:129:2:  [4] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused).
	strcpy (ret, str);
data/mpegdemux-0.1.4/src/mpeg_demux.c:47:11:  [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.

  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
