Examining data/ocurl-0.9.1/curl-helper.c

FINAL RESULTS:

data/ocurl-0.9.1/curl-helper.c:547:3:  [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(p,String_val(v),caml_string_length(v)+1); // caml strings have terminating zero
data/ocurl-0.9.1/curl-helper.c:554:3:  [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(&Byte(v,0),p,size);
data/ocurl-0.9.1/curl-helper.c:834:7:  [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(ptr, String_val(result), length);
data/ocurl-0.9.1/curl-helper.c:1080:91:  [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).
        Field(v_match, 0) = ml_copy_string(knownkey->key, knownkey->len ? knownkey->len : strlen(knownkey->key));
data/ocurl-0.9.1/curl-helper.c:1090:77:  [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).
    v_found = ml_copy_string(foundkey->key, foundkey->len ? foundkey->len : strlen(foundkey->key));
