FINAL RESULTS:

data/pps-tools-1.0.2/ppsctl.c:159:7:  [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.
		c = getopt_long(argc, argv, "bBfFach", long_options, &option_index);
data/pps-tools-1.0.2/ppswatch.c:182:7:  [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.
		c = getopt_long(argc, argv, "acm:h", long_options, &option_index);
data/pps-tools-1.0.2/ppsctl.c:47:8:  [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).
