FINAL RESULTS:

data/lua-rexlib-2.7.2/src/pcre/lpcre.c:198:5:  [4] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused).
    strcpy (old_locale, setlocale (LC_CTYPE, NULL));  /* store the locale */
data/lua-rexlib-2.7.2/src/common.c:169:5:  [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 (buf->arr + buf->top, src, sz);
data/lua-rexlib-2.7.2/src/gnu/lgnu.c:116:18:  [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.

  functions that limit length, or ensure that the size is larger than the

  char buf [ONIG_MAX_ERROR_MESSAGE_LEN];
data/lua-rexlib-2.7.2/src/oniguruma/lonig.c:342:33:  [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).
