Examining data/inputlirc-33/inputlircd.c

FINAL RESULTS:

data/inputlirc-33/inputlircd.c:262:4:  [5] (race) chmod:
  This accepts filename arguments; if an attacker can move those files, a
  race condition results. (CWE-362). Use fchmod( ) instead.
			chmod(dir, 0755);
data/inputlirc-33/inputlircd.c:277:2:  [5] (race) chmod:
  This accepts filename arguments; if an attacker can move those files, a
  race condition results. (CWE-362). Use fchmod( ) instead.
	chmod(device, 0666);
data/inputlirc-33/inputlircd.c:446:15:  [3] (buffer) getopt:
  Some older implementations do not protect against internal buffer overflows
  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
	while((opt = getopt(argc, argv, "cd:gm:n:fu:r:t:")) != -1) {
data/inputlirc-33/inputlircd.c:93:2:  [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 event_name[100];
data/inputlirc-33/inputlircd.c:94:2:  [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 lirc_name[100];
data/inputlirc-33/inputlircd.c:100:10:  [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).
	table = fopen(path, "r");
data/inputlirc-33/inputlircd.c:142:7:  [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(name, O_RDONLY);
data/inputlirc-33/inputlircd.c:209:2:  [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 name[32];
data/inputlirc-33/inputlircd.c:223:8:  [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(g.gl_pathv[i], O_RDONLY);
data/inputlirc-33/inputlircd.c:312:2:  [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 message[1000];
data/inputlirc-33/inputlircd.c:458:15:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
				key_min = atoi(optarg);
data/inputlirc-33/inputlircd.c:471:19:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
				repeat_time = atoi(optarg) * 1000L;
data/inputlirc-33/inputlircd.c:107:7:  [1] (buffer) sscanf:
  It's unclear if the %s limit in the format string is small enough
  (CWE-120). Check that the limit is sufficiently small, or use a different
  input function.
		if (sscanf(line, " %99s = %99s ", event_name, lirc_name) != 2)
data/inputlirc-33/inputlircd.c:112:6:  [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).
		if(strlen(event_name) < 1 || strlen(lirc_name) < 1)
data/inputlirc-33/inputlircd.c:112:32:  [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).
		if(strlen(event_name) < 1 || strlen(lirc_name) < 1)
data/inputlirc-33/inputlircd.c:268:2:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
	strncpy(sa.sun_path, device, sizeof sa.sun_path - 1);
data/inputlirc-33/inputlircd.c:316:5:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	if(read(evdev->fd, &event, sizeof event) != sizeof event) {
