  example, methods of 'zipfile.Path' like 'namelist()', 'iterdir()', etc) the process can be put
  into an infinite loop with a maliciously crafted zip archive. This defect applies when reading
  only metadata or extracting the contents of the zip archive.

  Note: this vulnerability only affects zipfile.Path, while the more common API zipfile.ZipFile
  class is unaffected.");
