* :mod:`xml`: :ref:`XML vulnerabilities <xml-vulnerabilities>`
* :mod:`zipfile`: :ref:`maliciously prepared .zip files can cause disk volume
exhaustion <zipfile-resources-limitations>`

The :option:`-I` command line option can be used to run Python in isolated

:envvar:`PYTHONSAFEPATH` environment variable can be used to not prepend a
potentially unsafe path to :data:`sys.path` such as the current directory, the
script's directory or an empty string.
