- Update to 3.9.20: - Tests - gh-112769: The tests now correctly compare zlib version when :const:`zlib.ZLIB_RUNTIME_VERSION` contains non-integer suffixes. For example zlib-ng defines the version as ``1.3.0.zlib-ng``. - gh-117187: Fix XML tests for vanilla Expat <2.6.0. - Security - gh-123678: Upgrade libexpat to 2.6.3 - gh-121957: Fixed missing audit events around interactive use of Python, now also properly firing for ``python -i``, as well as for ``python -m asyncio``. The event in question is ``cpython.run_stdin``. - gh-122133: Authenticate the socket connection for the ``socket.socketpair()`` fallback on platforms where ``AF_UNIX`` is not available like Windows. Patch by Gregory P. Smith <greg@krypto.org> and Seth Larson <seth@python.org>. Reported by Ellie <el@horse64.org> - gh-121285: Remove backtracking from tarfile header parsing for ``hdrcharset``, PAX, and GNU sparse headers (bsc#1230227, CVE-2024-6232). - gh-118486: :func:`os.mkdir` on Windows now accepts *mode* of ``0o700`` to restrict the new directory to the current user. This fixes CVE-2024-4030 affecting :func:`tempfile.mkdtemp` in scenarios where the base temporary directory is more permissive than the default. - gh-114572: :meth:`ssl.SSLContext.cert_store_stats` and :meth:`ssl.SSLContext.get_ca_certs` now correctly lock access to the certificate store, when the :class:`ssl.SSLContext` is shared across multiple threads (bsc#1226447, CVE-2024-0397). - gh-116741: Update bundled libexpat to 2.6.2 - Library - gh-123270: Applied a more surgical fix for malformed payloads in OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:Factory/python39?expand=0&rev=201

Update to 3.9.25 Security - gh-137836: Add support of the “plaintext” element, RAWTEXT elements “xmp”, “iframe”, “noembed” and “noframes”, and optionally RAWTEXT element “noscript” in html.parser.HTMLParser. - gh-136063: email.message: ensure linear complexity for legacy HTTP parameters parsing. Patch by Bénédikt Tran. - gh-136065: Fix quadratic complexity in os.path.expandvars() (CVE-2025-6075, bsc#1252974). Library - gh-98793: Fix argument typechecks in _overlapped.WSAConnect() and _overlapped.Overlapped.WSASendTo() functions. bpo-44817: Ignore WinError 53 (ERROR_BAD_NETPATH), 65 (ERROR_NETWORK_ACCESS_DENIED) and 161 (ERROR_BAD_PATHNAME) when using ntpath.realpath(). Core and Builtins - gh-120384: Fix an array out of bounds crash in list_ass_subscript, which could be invoked via some specificly tailored input: including concurrent modification of a list object, where one thread assigns a slice and another clears it. - gh-120298: Fix use-after free in list_richcompare_impl which can be invoked via some specificly tailored evil input.
