Examining data/asmixer-0.5/asmixer.c

FINAL RESULTS:

data/asmixer-0.5/asmixer.c:355:5:  [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(&device[0], argv[i]);
data/asmixer-0.5/asmixer.c:360:5:  [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(&wintitle[0], argv[i]);
data/asmixer-0.5/asmixer.c:72:1:  [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    wintitle[128] = DEFAULTTITLE;
data/asmixer-0.5/asmixer.c:81:1:  [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    device[128]=DEFAULTDEVICE;
data/asmixer-0.5/asmixer.c:107:7:  [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).
   fd=open(device,0);
data/asmixer-0.5/asmixer.c:141:4:  [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).
fd=open(device,0);
data/asmixer-0.5/asmixer.c:162:4:  [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).
fd=open(device,0);
data/asmixer-0.5/asmixer.c:309:4:  [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[MAX_LINE_NAME];
data/asmixer-0.5/asmixer.c:333:2:  [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 WhichLine[MAX_LINE_NAME];
data/asmixer-0.5/asmixer.c:367:5:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
				strncpy(WhichLine, argv[i], MAX_LINE_NAME-1);
data/asmixer-0.5/asmixer.c:381:5:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
				strncpy(WhichLine, argv[i], MAX_LINE_NAME-1);
data/asmixer-0.5/asmixer.c:382:16:  [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).
				for(j=1;j<=strlen(WhichLine);j++)
data/asmixer-0.5/asmixer.c:383:48:  [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).
				  CmdVol=CmdVol+(WhichLine[j-1]-48)*pow(10,strlen(WhichLine)-j);
data/asmixer-0.5/asmixer.c:448:2:  [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(250000L);
