This update for python311 fixes the following issues: - CVE-2025-4516: Fixed blocking DecodeError handling vulnerability, which could lead to DoS. (bsc#1243273) Update to 3.11.12: - gh-105704: When using urllib.parse.urlsplit() and urllib.parse.urlparse() host parsing would not reject domain names containing square brackets ([ and ]). Square brackets are only valid for IPv6 and IPvFuture hosts according to RFC 3986 Section 3.2.2 (bsc#1236705, CVE-2025-0938, gh#python/cpython#105704). - gh-121284: Fix bug in the folding of rfc2047 encoded-words when flattening an email message using a modern email policy. Previously when an encoded-word was too long for a line, it would be decoded, split across lines, and re-encoded. But commas and other special characters in the original text could be left unencoded and unquoted. This could theoretically be used to spoof header lines using a carefully constructed encoded-word if the resulting rendered email was transmitted or re-parsed. - gh-80222: Fix bug in the folding of quoted strings when flattening an email message using a modern email policy. Previously when a quoted string was folded so that it spanned more than one line, the surrounding quotes and internal escapes would be omitted. This could theoretically be used to spoof header lines using a carefully constructed quoted string if the resulting rendered email was transmitted or re-parsed. - gh-119511: Fix a potential denial of service in the imaplib module. When connecting to a malicious server, it could cause an arbitrary amount of memory to be allocated. On many systems this is harmless as unused virtual memory is only a mapping, but if this hit a virtual address size limit it could lead to a MemoryError or other process crash. On unusual systems or builds where all allocated memory is touched and backed by actual ram or storage it could’ve consumed resources doing so until similarly crashing. - gh-127257: In ssl, system call failures that OpenSSL reports using ERR_LIB_SYS are now raised as OSError. - gh-121277: Writers of CPython’s documentation can now use next as the version for the versionchanged, versionadded, deprecated directives. - gh-106883: Disable GC during the _PyThread_CurrentFrames() and _PyThread_CurrentExceptions() calls to avoid the interpreter to deadlock. - CVE-2025-0938: disallow square brackets ([ and ]) in domain names for parsed URLs (bsc#1236705, gh#python/cpython#105704) Update to 3.11.11: - Tools/Demos - gh-123418: Update GitHub CI workflows to use OpenSSL 3.0.15 and multissltests to use 3.0.15, 3.1.7, and 3.2.3. - Security - gh-122792: Changed IPv4-mapped ipaddress.IPv6Address to consistently use the mapped IPv4 address value for deciding properties. Properties which have their behavior fixed are is_multicast, is_reserved, is_link_local, is_global, and is_unspecified. - Library - gh-124651: Properly quote template strings in venv activation scripts (bsc#1232241, CVE-2024-9287). - Remove -IVendor/ from python-config bsc#1231795 - CVE-2024-9287: Properly quote path names provided when creating a virtual environment (bsc#1232241, - Drop .pyc files from docdir for reproducible builds (bsc#1230906). Update to 3.11.10: - Security - 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 <[email protected]> and Seth Larson <[email protected]>. Reported by Ellie <[email protected]> - 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. - Library - gh-123270: Applied a more surgical fix for malformed payloads in :class:`zipfile.Path` causing infinite loops (gh-122905) without breaking contents using legitimate characters (bsc#1229704, CVE-2024-8088). - gh-123067: Fix quadratic complexity in parsing ``"``-quoted cookie values with backslashes by :mod:`http.cookies` (bsc#1229596, CVE-2024-7592). - gh-122905: :class:`zipfile.Path` objects now sanitize names from the zipfile. - gh-121650: :mod:`email` headers with embedded newlines are now quoted on output. The :mod:`~email.generator` will now refuse to serialize (write) headers that are unsafely folded or delimited; see :attr:`~email.policy.Policy.verify_generated_headers`. (Contributed by Bas Bloemsaat and Petr Viktorin in :gh:`121650`; CVE-2024-6923, bsc#1228780). - gh-119506: Fix :meth:`!io.TextIOWrapper.write` method breaks internal buffer when the method is called again during flushing internal buffer. - gh-118643: Fix an AttributeError in the :mod:`email` module when re-fold a long address list. Also fix more cases of incorrect encoding of the address separator in the address list. - gh-113171: Fixed various false positives and false negatives in * :attr:`ipaddress.IPv4Address.is_private` (see these docs for details) * :attr:`ipaddress.IPv4Address.is_global` * :attr:`ipaddress.IPv6Address.is_private` * :attr:`ipaddress.IPv6Address.is_global` Also in the corresponding :class:`ipaddress.IPv4Network` and :class:`ipaddress.IPv6Network` attributes. Fixes bsc#1226448 (CVE-2024-4032). - gh-102988: :func:`email.utils.getaddresses` and :func:`email.utils.parseaddr` now return ``('', '')`` 2-tuples in more situations where invalid email addresses are encountered instead of potentially inaccurate values. Add optional *strict* parameter to these two functions: use ``strict=False`` to get the old behavior, accept malformed inputs. ``getattr(email.utils, 'supports_strict_parsing', False)`` can be use to check if the *strict* paramater is available. Patch by Thomas Dwyer and Victor Stinner to improve the CVE-2023-27043 fix (bsc#1210638). - gh-67693: Fix :func:`urllib.parse.urlunparse` and :func:`urllib.parse.urlunsplit` for URIs with path starting with multiple slashes and no authority. Based on patch by Ashwin Ramaswami. - Core and Builtins - gh-112275: A deadlock involving ``pystate.c``'s ``HEAD_LOCK`` in ``posixmodule.c`` at fork is now fixed. Patch by ChuBoning based on previous Python 3.12 fix by Victor Stinner. - gh-109120: Added handle of incorrect star expressions, e.g ``f(3, *)``. Patch by Grigoryev Semyon - CVE-2024-8088: Prevent malformed payload to cause infinite loops in zipfile.Path (bsc#1229704) - Make pip and modern tools install directly in /usr/local when used by the user. (bsc#1225660) - CVE-2024-4032: Fix rearranging definition of private v global IP addresses. (bsc#1226448) Update to 3.11.9: * Security - gh-115398: Allow controlling Expat >=2.6.0 reparse deferral (CVE-2023-52425, bsc#1219559) by adding five new methods: xml.etree.ElementTree.XMLParser.flush() xml.etree.ElementTree.XMLPullParser.flush() xml.parsers.expat.xmlparser.GetReparseDeferralEnabled() xml.parsers.expat.xmlparser.SetReparseDeferralEnabled() xml.sax.expatreader.ExpatParser.flush()
