FINAL RESULTS:

data/hyantesite-1.3.0/src/hyantes.c:142:12:  [4] (buffer) fscanf:
  The scanf() family's %s operation, without a limit specification, permits
  buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a
  different input function. If the scanf format is influenceable by an
  attacker, it's exploitable.
        if(fscanf(fd,INPUT_FORMAT,&the_towns[curr].lat,&the_towns[curr].lon,&the_towns[curr].pot) !=3 )
data/hyantesite-1.3.0/src/hyantes.c:185:13:  [4] (format) printf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
            printf(OUTPUT_FORMAT,pt[i][j].lon,pt[i][j].lat,pt[i][j].pot);
data/hyantesite-1.3.0/bin/hyantesite.c:157:11:  [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.
          getopt_long(argc, argv, short_options, long_options,
data/hyantesite-1.3.0/bin/hyantesite.c:131:5:  [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 short_options[1 +
data/hyantesite-1.3.0/bin/hyantesite.c:197:18:  [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).
            fi = fopen(optarg, "r");

            fo = fopen(optarg, "w");
data/hyantesite-1.3.0/bin/hyantesite.c:230:30:  [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).
                    resLat = atoi(res);
data/hyantesite-1.3.0/bin/hyantesite.c:238:30:  [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).
                    resLon = atoi(res);
data/hyantesite-1.3.0/test/hyantesite_status.c:38:10:  [2] (misc) fopen:
  Check when opening files - can an attacker redirect it (via symlinks),

data/hyantesite-1.3.0/test/hyantesite_status.c:49:17:  [2] (integer) atoi:

       resLon = atoi(argv[8]),  /* resLon */
data/hyantesite-1.3.0/src/hyantes.c:146:30:  [1] (buffer) fgetc:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
                char c=(char)fgetc(fd);
