FINAL RESULTS:

data/farpd-0.2/arpd.c:506:2:  [5] (race) chmod:
  This accepts filename arguments; if an attacker can move those files, a
  race condition results. (CWE-362). Use fchmod( ) instead.
	chmod(PIDFILE, 0644);
data/farpd-0.2/arpd.c:471:14:  [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 ((c = getopt(argc, argv, "di:h?")) != -1) {
data/farpd-0.2/arpd.c:85:9:  [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.
	static char filter[1024];
data/farpd-0.2/arpd.c:86:2:  [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 line[1024], *p;
data/farpd-0.2/arpd.c:138:5:  [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 single[32];
data/farpd-0.2/arpd.c:188:2:  [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 filter[1024], ebuf[PCAP_ERRBUF_SIZE], *dst;
data/farpd-0.2/arpd.c:289:2:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
	memcpy(&arpent.arp_pa, addr, sizeof(*addr));
data/farpd-0.2/arpd.c:328:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
		memcpy(&req->ha, ha, sizeof(*ha));
data/farpd-0.2/arpd.c:379:4:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
			memcpy(&req->pa, &tmp.pa, sizeof(tmp.pa));
data/farpd-0.2/arpd.c:492:12:  [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 ((fp = fopen(PIDFILE, "w")) == NULL)
data/farpd-0.2/daemon.c:58:27:  [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).
    if (!noclose && (fd = open("/dev/null", O_RDWR, 0)) != -1) {
data/farpd-0.2/arpd.c:206:2:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
	strncpy(arpd_ifent.intf_name, dev, sizeof(arpd_ifent.intf_name) - 1);
