FINAL RESULTS:

data/mwparserfromhell-0.5.4/mwparserfromhell/parser/ctokenizer/tok_parse.c:1026:9:  [4] (buffer) sscanf:
  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.
        sscanf(text, (hexadecimal ? "%x" : "%d"), &test);
data/mwparserfromhell-0.5.4/mwparserfromhell/parser/ctokenizer/tok_parse.c:1050:9:  [4] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused).
        strcat(buffer, text);
data/mwparserfromhell-0.5.4/mwparserfromhell/parser/ctokenizer/textbuffer.c:78:5:  [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(newdata, self->data, self->length * self->kind);
data/mwparserfromhell-0.5.4/mwparserfromhell/parser/ctokenizer/textbuffer.c:201:5:  [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(((Py_UCS1*) self->data) + self->kind * self->length, other->data,
data/mwparserfromhell-0.5.4/mwparserfromhell/parser/ctokenizer/textbuffer.c:204:5:  [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(self->data + self->length, other->data,
data/mwparserfromhell-0.5.4/mwparserfromhell/parser/ctokenizer/tok_parse.c:204:17:  [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 text[MAX_BRACES + 1];
data/mwparserfromhell-0.5.4/mwparserfromhell/parser/ctokenizer/tok_parse.c:1042:25:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
        buffer = calloc(strlen(text) + zeroes + 1, sizeof(char));
data/mwparserfromhell-0.5.4/mwparserfromhell/parser/ctokenizer/tok_parse.c:1049:13:  [1] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused). Risk is low because the
  source is a constant character.
            strcat(buffer, "0");
data/mwparserfromhell-0.5.4/mwparserfromhell/parser/ctokenizer/tok_parse.c:2115:30:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
    if (close_open_markup && strlen(close_open_markup) != 0) {
data/mwparserfromhell-0.5.4/mwparserfromhell/parser/ctokenizer/tok_parse.c:2346:19:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
    self->head += strlen(markup);
