Fixed an issue where instances of :class:`ssl.SSLSocket` were vulnerable to
|
|
a bypass of the TLS handshake and included protections (like certificate
|
|
verification) and treating sent unencrypted data as if it were
|
|
post-handshake TLS encrypted data. Security issue reported as
|
|
`CVE-2023-40217

|
<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-40217>`_ by Aapo

Restore following CPython <= 3.10.5 behavior of :func:`shutil.make_archive`:

do not create an empty archive if ``root_dir`` is not a directory, and, in

that case, raise :class:`FileNotFoundError` or :class:`NotADirectoryError`
|

regardless of ``format`` choice. Beyond the brought-back behavior, the

function may now also raise these exceptions in ``dry_run`` mode.
