Examining data/asmix-1.5/asmix.c

FINAL RESULTS:

data/asmix-1.5/asmix.c:307:2:  [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(&Execute[0], argv[i]);
data/asmix-1.5/asmix.c:515:13:  [4] (shell) system:
  This causes a new program to execute and is difficult to use safely
  (CWE-78). try using a library call that implements the same functionality
  if available.
	           system(Execute);
data/asmix-1.5/asmix.c:580:6:  [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.
    {fprintf(stderr, ERR_colorcells);exit(1);}
data/asmix-1.5/asmix.c:587:6:  [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.
    {fprintf(stderr, ERR_colorcells);exit(1);}
data/asmix-1.5/asmix.c:308:2:  [2] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused). Risk is low because the
  source is a constant string.
	strcat(&Execute[0], " &");
data/asmix-1.5/asmix.c:360:14:  [2] (misc) open:
  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).
  mixer_fd = open (mixer_device, O_RDWR, 0);   
data/asmix-1.5/asmix.c:552:7:  [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.
      usleep(50000L);			/* 50/100 sec */
