FINAL RESULTS:

data/ruby-ffi-yajl-2.3.1/ext/ffi_yajl/ext/dlopen/dlopen.c:17:38:  [3] (misc) LoadLibrary:
  Ensure that the full path to the library is specified, or current directory
  may be used (CWE-829, CWE-20). Use registry entry or GetWindowsDirectory to
  find library path, if you aren't already.
#   define dlopen(name,flag) ((void*)LoadLibrary(name))
data/ruby-ffi-yajl-2.3.1/ext/ffi_yajl/ext/parser/parser.c:86:3:  [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(buf, numberVal, numberLen);
