FINAL RESULTS:

data/mythes-1.2.4/example.cxx:37:12:  [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).
  wtclst = fopen(argv[3], "r");
data/mythes-1.2.4/example.cxx:55:5:  [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 buf[101];
data/mythes-1.2.4/example.cxx:56:5:  [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 oldbuf[101];
data/mythes-1.2.4/mythes.cxx:38:21:  [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).
    FILE * pifile = fopen(idxpath,"r");
data/mythes-1.2.4/mythes.cxx:49:17:  [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).
    int idxsz = atoi(wrd); 
data/mythes-1.2.4/mythes.cxx:82:17:  [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((list[nw]),wrd,np);
data/mythes-1.2.4/mythes.cxx:83:29:  [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;

  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).

data/mythes-1.2.4/mythes.cxx:154:5:  [2] (buffer) memcpy:

    memcpy(wrd,pText,len);
data/mythes-1.2.4/mythes.cxx:178:21:  [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).

data/mythes-1.2.4/mythes.cxx:189:5:  [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
