FINAL RESULTS:

data/dublin-traceroute-0.4.2/src/main.cc:96:17:  [3] (buffer) getopt_long:
  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 ((iarg = getopt_long(argc, argv, shortopts, longopts, &index)) != -1) {
data/dublin-traceroute-0.4.2/src/dublin_traceroute.cc:147:4:  [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 buf[512];
data/dublin-traceroute-0.4.2/src/hop.cc:58:2:  [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

	char host[NI_MAXHOST], service[NI_MAXSERV];
data/dublin-traceroute-0.4.2/src/main.cc:213:11:  [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).
