Examining data/atmel-firmware-1.3/atmel_fwl.c

FINAL RESULTS:

data/atmel-firmware-1.3/atmel_fwl.c:115:2:  [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(ifr.ifr_ifrn.ifrn_name, argv[1]);
data/atmel-firmware-1.3/atmel_fwl.c:35:2:  [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 id[32];
data/atmel-firmware-1.3/atmel_fwl.c:58:15:  [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).
	if (!(file = fopen(argv[2], "r"))) {
data/atmel-firmware-1.3/atmel_fwl.c:90:2:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
	strncpy(com.id, id, 31);
