Summary: Python Interpreter shared library |
Python is an interpreted, object-oriented programming language, and is often compared to Tcl, Perl, Scheme, or Java. You can find an overview of Python in the documentation and tutorials included in the python-doc (HTML) or python-doc-pdf (PDF) packages. This package contains libpython3.2 shared library for embedding in other applications.
Python-2.0
* Fri Sep 20 2024 Matej Cepl <mcepl@cepl.eu> - Add sphinx-802.patch to overcome working both with the most recent and older Sphinx versions. * Mon Sep 09 2024 Matej Cepl <mcepl@cepl.eu> - 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 :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-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-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. - Remove upstreamed patches: - CVE-2023-27043-email-parsing-errors.patch - CVE-2024-6232-cookies-quad-complex.patch - CVE-2024-4032-private-IP-addrs.patch - CVE-2024-0397-memrace_ssl.SSLContext_cert_store.patch - CVE-2024-8088-inf-loop-zipfile_Path.patch - CVE-2024-6923-email-hdr-inject.patch * Thu Sep 05 2024 Matej Cepl <mcepl@cepl.eu> - Add CVE-2024-6232-cookies-quad-complex.patch to avoid quadratic complexity in parsing tarfile headers (bsc#1230227, CVE-2024-6232). * Thu Sep 05 2024 Matej Cepl <mcepl@cepl.eu> - Add CVE-2023-52425-libexpat-2.6.0-backport.patch to fix tests with patched libexpat below 2.6.0 that doesn't update the version number, just in SLE. - Remove old-libexpat.patch, of course. * Mon Sep 02 2024 Matej Cepl <mcepl@cepl.eu> - Add gh120226-fix-sendfile-test-kernel-610.patch to avoid failing test_sendfile_close_peer_in_the_middle_of_receiving tests on Linux >= 6.10 (GH-120227). * Wed Aug 28 2024 Matej Cepl <mcepl@cepl.eu> - Add CVE-2024-8088-inf-loop-zipfile_Path.patch to prevent malformed payload to cause infinite loops in zipfile.Path (bsc#1229704, CVE-2024-8088). * Wed Aug 07 2024 Matej Cepl <mcepl@suse.com> - Add CVE-2024-6923-email-hdr-inject.patch to prevent email header injection due to unquoted newlines (bsc#1228780, CVE-2024-6923). - Adding bso1227999-reproducible-builds.patch fixing bsc#1227999 adding reproducibility patches from gh#python/cpython!121872 and gh#python/cpython!121883. - Add CVE-2024-5642-OpenSSL-API-buf-overread-NPN.patch removing support for anything but OpenSSL 1.1.1 or newer (bsc#1227233, CVE-2024-5642). - %{profileopt} variable is set according to the variable %{do_profiling} (bsc#1227999) * Mon Jul 22 2024 Matej Cepl <mcepl@cepl.eu> - Remove %suse_update_desktop_file macro as it is not useful any more. * Mon Jul 15 2024 Matej Cepl <mcepl@cepl.eu> - Stop using %%defattr, it seems to be breaking proper executable attributes on /usr/bin/ scripts (bsc#1227378). * Wed Jun 26 2024 Matej Cepl <mcepl@cepl.eu> - Add CVE-2024-4032-private-IP-addrs.patch to fix bsc#1226448 (CVE-2024-4032) rearranging definition of private v global IP addresses. * Fri Jun 21 2024 Matej Cepl <mcepl@cepl.eu> - Add CVE-2024-0397-memrace_ssl.SSLContext_cert_store.patch fixing bsc#1226447 (CVE-2024-0397) by removing memory race condition in ssl.SSLContext certificate store methods. * Sun Mar 24 2024 Matej Cepl <mcepl@cepl.eu> - Add old-libexpat.patch making the test suite work with libexpat < 2.6.0 (gh#python/cpython#117187). * Thu Mar 21 2024 Matej Cepl <mcepl@cepl.eu> - Update to 3.9.19: - 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() - gh-115399: Update bundled libexpat to 2.6.0 - gh-113659: Skip .pth files with names starting with a dot or hidden file attribute. - Core and Builtins - gh-102388: Fix a bug where iso2022_jp_3 and iso2022_jp_2004 codecs read out of bounds - Library - gh-115197: urllib.request no longer resolves the hostname before checking it against the system’s proxy bypass list on macOS and Windows. - gh-115133: Fix tests for XMLPullParser with Expat 2.6.0. - gh-81194: Fix a crash in socket.if_indextoname() with specific value (UINT_MAX). Fix an integer overflow in socket.if_indextoname() on 64-bit non-Windows platforms. - gh-109858: Protect zipfile from “quoted-overlap” zipbomb. It now raises BadZipFile when try to read an entry that overlaps with other entry or central directory (CVE-2024-0450, bsc#1221854). - gh-107077: Seems that in some conditions, OpenSSL will return SSL_ERROR_SYSCALL instead of SSL_ERROR_SSL when a certification verification has failed, but the error parameters will still contain ERR_LIB_SSL and SSL_R_CERTIFICATE_VERIFY_FAILED. We are now detecting this situation and raising the appropiate ssl.SSLCertVerificationError. Patch by Pablo Galindo - gh-91133: Fix a bug in tempfile.TemporaryDirectory cleanup, which now no longer dereferences symlinks when working around file system permission errors (CVE-2023-6597, bsc#1219666). - Documentation - gh-115399: Document CVE-2023-52425 of Expat <2.6.0 under “XML vulnerabilities”. - Tools/Demos - gh-109991: Update GitHub CI workflows to use OpenSSL 3.0.11 and multissltests to use 1.1.1w and 3.0.11. - Remove upstreamed patches: - CVE-2023-6597-TempDir-cleaning-symlink.patch - libexpat260.patch - Refreshed patches: - F00251-change-user-install-location.patch - python-3.3.0b1-localpath.patch * Wed Mar 06 2024 Pedro Monreal <pmonreal@suse.com> - Use the system-wide crypto-policies [bsc#1211301] * Use the system default cipher list instead of hardcoded values * Add the --with-ssl-default-suites=openssl configure option * Wed Feb 28 2024 Matej Cepl <mcepl@suse.com> - Update SPEC file to build on SLE-15-SP5 (jsc#PED-7886). * Fri Feb 23 2024 Matej Cepl <mcepl@suse.com> - (bsc#1219666, CVE-2023-6597) Add CVE-2023-6597-TempDir-cleaning-symlink.patch (patch from gh#python/cpython!99930) fixing symlink bug in cleanup of tempfile.TemporaryDirectory. - Repurpose skip-failing-tests.patch to increase timeout for test.test_asyncio.test_tasks.TimeoutTests.test_timeout_time, which fails on slow machines in IBS (s390x). * Tue Feb 20 2024 Matej Cepl <mcepl@cepl.eu> - Remove double definition of /usr/bin/idle%%{version} in %%files. * Thu Feb 15 2024 Daniel Garcia <daniel.garcia@suse.com> - Add upstream patch libexpat260.patch, Fix tests for XMLPullParser with Expat 2.6.0, gh#python/cpython#115289 * Mon Dec 18 2023 Matej Cepl <mcepl@cepl.eu> - Refresh CVE-2023-27043-email-parsing-errors.patch to gh#python/cpython!111116, fixing bsc#1210638 (CVE-2023-27043). - Thus we can remove Revert-gh105127-left-tests.patch, which is now useless. * Wed Sep 06 2023 Daniel Garcia <daniel.garcia@suse.com> - Update to 3.9.18 (bsc#1214692): - (bsc#1215454, gh-108310) Fixed an issue where instances of 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 by Aapo Oksman. Patch by Gregory P. Smith. - gh-107845: tarfile.data_filter() now takes the location of symlinks into account when determining their target, so it will no longer reject some valid tarballs with LinkOutsideDestinationError. - gh-107565: Update multissltests and GitHub CI workflows to use OpenSSL 1.1.1v, 3.0.10, and 3.1.2. - Refresh all patches: - 98437-sphinx.locale._-as-gettext-in-pyspecific.patch - 99366-patch.dict-can-decorate-async.patch - Revert-gh105127-left-tests.patch - bpo-31046_ensurepip_honours_prefix.patch - decimal.patch - distutils-reproducible-compile.patch - gh-78214-marshal_stabilize_FLAG_REF.patch - python-3.3.0b1-localpath.patch - python-3.3.0b1-test-posix_fadvise.patch - python3-imp-returntype.patch - subprocess-raise-timeout.patch - support-expat-CVE-2022-25236-patched.patch - downport-Sphinx-features.patch * Thu Aug 03 2023 Matej Cepl <mcepl@suse.com> - IT MEANS THAT bsc#1210638 STILL HAS NOT BEEN FIXED! - Add Revert-gh105127-left-tests.patch (gh#python/cpython!106941) partially reverting CVE-2023-27043-email-parsing-errors.patch, because of the regression in gh#python/cpython#106669. - (bsc#1210638, CVE-2023-27043) Add CVE-2023-27043-email-parsing-errors.patch, which detects email address parsing errors and returns empty tuple to indicate the parsing error (old API).

See Extraction filters for details (fixing CVE-2007-4559, bsc#1203750). - gh-102126: Fixed a deadlock at shutdown when clearing thread states if any finalizer tries to acquire the runtime head lock. - gh-100892: Fixed a crash due to a race while iterating over thread states in clearing threading.local. - Remove upstreamed patches: - CVE-2023-24329-blank-URL-bypass.patch - CVE-2007-4559-filter-tarfile_extractall.patch * Sat May 06 2023 Matej Cepl <mcepl@suse.com> - Add 99366-patch.dict-can-decorate-async.patch fixing gh#python/cpython#98086 (backport from Python 3.10 patch in gh#python/cpython!99366), fixing bsc#1211158. * Wed May 03 2023 Matej Cepl <mcepl@suse.com> - Add CVE-2007-4559-filter-tarfile_extractall.patch to fix CVE-2007-4559 (bsc#1203750) by adding the filter for tarfile.extractall (PEP 706). * Tue Apr 18 2023 Steve Kowalik <steven.kowalik@suse.com> - Use python3 modules to build the documentation. * Wed Mar 01 2023 Matej Cepl <mcepl@suse.com> - Add CVE-2023-24329-blank-URL-bypass.patch (CVE-2023-24329, bsc#1208471) blocklists bypass via the urllib.parse component when supplying a URL that starts with blank characters * Tue Feb 21 2023 Matej Cepl <mcepl@suse.com> - Add provides for readline and sqlite3 to the main Python package. * Fri Jan 27 2023 Thorsten Kukuk <kukuk@suse.com> - Disable NIS for new products, it's deprecated and gets removed * Fri Jan 13 2023 Martin Liška <mliska@suse.cz> - Suppress warnings for Sphinx 6.0+. * Thu Dec 08 2022 Matej Cepl <mcepl@suse.com> - Update to 3.9.16: - python -m http.server no longer allows terminal control characters sent within a garbage request to be printed to the stderr server log. This is done by changing the http.server BaseHTTPRequestHandler .log_message method to replace control characters with a \xHH hex escape before printing. - Avoid publishing list of active per-interpreter audit hooks via the gc module - The IDNA codec decoder used on DNS hostnames by socket or asyncio related name resolution functions no longer involves a quadratic algorithm. This prevents a potential CPU denial of service if an out-of-spec excessive length hostname involving bidirectional characters were decoded. Some protocols such as urllib http 3xx redirects potentially allow for an attacker to supply such a name (CVE-2015-20107). - Update bundled libexpat to 2.5.0 - Port XKCP’s fix for the buffer overflows in SHA-3 (CVE-2022-37454). - On Linux the multiprocessing module returns to using filesystem backed unix domain sockets for communication with the forkserver process instead of the Linux abstract socket namespace. Only code that chooses to use the “forkserver” start method is affected. Abstract sockets have no permissions and could allow any user on the system in the same network namespace (often the whole system) to inject code into the multiprocessing forkserver process. This was a potential privilege escalation. Filesystem based socket permissions restrict this to the forkserver process user as was the default in Python 3.8 and earlier. This prevents Linux CVE-2022-42919. - The deprecated mailcap module now refuses to inject unsafe text (filenames, MIME types, parameters) into shell commands. Instead of using such text, it will warn and act as if a match was not found (or for test commands, as if the test failed). - Removed upstreamed patches: - CVE-2015-20107-mailcap-unsafe-filenames.patch - CVE-2022-42919-loc-priv-mulitproc-forksrv.patch - CVE-2022-45061-DoS-by-IDNA-decode.patch * Wed Nov 09 2022 Matej Cepl <mcepl@suse.com> - Add CVE-2022-45061-DoS-by-IDNA-decode.patch to avoid CVE-2022-45061 (bsc#1205244) allowing DoS by IDNA decoding extremely long domain names. * Thu Nov 03 2022 Matej Cepl <mcepl@suse.com> - Add CVE-2022-42919-loc-priv-mulitproc-forksrv.patch to avoid CVE-2022-42919 (bsc#1204886) avoiding Linux specific local privilege escalation via the multiprocessing forkserver start method. * Fri Oct 21 2022 Matej Cepl <mcepl@suse.com> - Add 98437-sphinx.locale._-as-gettext-in-pyspecific.patch to allow building of documentation with the latest Sphinx 5.3.0 (gh#python/cpython#98366). * Wed Oct 19 2022 Matej Cepl <mcepl@suse.com> - Update to 3.9.15: - Fix multiplying a list by an integer (list *= int): detect the integer overflow when the new allocated length is close to the maximum size. - Fix a shell code injection vulnerability in the get-remote-certificate.py example script. The script no longer uses a shell to run openssl commands. (originally filed as CVE-2022-37460, later withdrawn) - Fix command line parsing: reject -X int_max_str_digits option with no value (invalid) when the PYTHONINTMAXSTRDIGITS environment variable is set to a valid limit. - When ValueError is raised if an integer is larger than the limit, mention the sys.set_int_max_str_digits() function in the error message. - Update bundled libexpat to 2.4.9 * Sun Sep 11 2022 Matej Cepl <mcepl@suse.com> - Update to 3.9.14: - (CVE-2020-10735, bsc#1203125). Converting between int and str in bases other than 2 (binary), 4, 8 (octal), 16 (hexadecimal), or 32 such as base 10 (decimal) now raises a ValueError if the number of digits in string form is above a limit to avoid potential denial of service attacks due to the algorithmic complexity. This new limit can be configured or disabled by environment variable, command line flag, or sys APIs. See the integer string conversion length limitation documentation. The default limit is 4300 digits in string form. - Also other bug fixes: - http.server: Fix an open redirection vulnerability in the HTTP server when an URI path starts with //. Vulnerability discovered, and initial fix proposed, by Hamza Avvan. - Fix contextvars HAMT implementation to handle iteration over deep trees. The bug was discovered and fixed by Eli Libman. See MagicStack/immutables#84 for more details. - Fix binding of unix socket to empty address on Linux to use an available address from the abstract namespace, instead of “0”. - Suppress writing an XML declaration in open files in ElementTree.write() with encoding='unicode' and xml_declaration=None. - Fix the formatting for await x and not x in the operator precedence table when using the help() system. - Fix ensurepip environment isolation for subprocess running pip. - Fix problem with test_ssl test_get_ciphers on systems that require perfect forward secrecy (PFS) ciphers. - test_ssl is now checking for supported TLS version and protocols in more tests. - Removed upstreamed patches: - CVE-2021-28861-double-slash-path.patch - Realign patches: - bpo-31046_ensurepip_honours_prefix.patch - sphinx-update-removed-function.patch * Thu Sep 01 2022 Steve Kowalik <steven.kowalik@suse.com> - Add patch CVE-2021-28861-double-slash-path.patch: * http.server: Fix an open redirection vulnerability in the HTTP server when an URI path starts with //.

When a subinterpreter is deleted, untrack all objects tracked by its GC. To prevent a crash in deallocator functions expecting objects to be tracked by the GC, leak a strong reference to these objects on purpose, so they are never deleted and their deallocator functions are not called. Patch by Victor Stinner. - gh-91421: Fix a potential integer overflow in _Py_DecodeUTF8Ex. - bpo-46775: Some Windows system error codes(>= 10000) are now mapped into the correct errno and may now raise a subclass of OSError. Patch by Dong-hee Na. - bpo-46962: Classes and functions that unconditionally declared their docstrings ignoring the - -without-doc-strings compilation flag no longer do so. - The classes affected are pickle.PickleBuffer, testcapi.RecursingInfinitelyError, and types.GenericAlias. - The functions affected are 24 methods in ctypes. - Patch by Oleg Iarygin. - bpo-36819: Fix crashes in built-in encoders with error handlers that return position less or equal than the starting position of non-encodable characters. - Library - gh-91581: utcfromtimestamp() no longer attempts to resolve fold in the pure Python implementation, since the fold is never 1 in UTC. In addition to being slightly faster in the common case, this also prevents some errors when the timestamp is close to datetime.min. Patch by Paul Ganssle. - gh-92530: Fix an issue that occurred after interrupting threading.Condition.notify(). - gh-92049: Forbid pickling constants re._constants.SUCCESS etc. Previously, pickling did not fail, but the result could not be unpickled. - bpo-47029: Always close the read end of the pipe used by multiprocessing.Queue after the last write of buffered data to the write end of the pipe to avoid BrokenPipeError at garbage collection and at multiprocessing.Queue.close() calls. Patch by Géry Ogam. - gh-91910: Add missing f prefix to f-strings in error messages from the multiprocessing and asyncio modules. - gh-91810: ElementTree method write() and function tostring() now use the text file’s encoding (“UTF-8” if not available) instead of locale encoding in XML declaration when encoding="unicode" is specified. - gh-91832: Add required attribute to argparse.Action repr output. - gh-91734: Fix OSS audio support on Solaris. - gh-91700: Compilation of regular expression containing a conditional expression (?(group)...) now raises an appropriate re.error if the group number refers to not defined group.

Patch by Yu Liu. - gh-90622: Worker processes for concurrent.futures.ProcessPoolExecutor are no longer spawned on demand (a feature added in 3.9) when the multiprocessing context start method is "fork" as that can lead to deadlocks in the child processes due to a fork happening while threads are running. - gh-91575: Update case-insensitive matching in the re module to the latest Unicode version. - gh-91581: Remove an unhandled error case in the C implementation of calls to datetime.fromtimestamp with no time zone (i.e. getting a local time from an epoch timestamp). This should have no user-facing effect other than giving a possibly more accurate error message when called with timestamps that fall on 10000-01-01 in the local time. Patch by Paul Ganssle. - bpo-34480: Fix a bug where _markupbase raised an UnboundLocalError when an invalid keyword was found in marked section.

Patch by Pablo Galindo - Fix a crash at Python exit when a deallocator function removes the last strong reference to a heap type. Patch by Victor Stinner. - Fix crash when using passing a non-exception to a generator’s throw() method. Patch by Noah Oxer - Library - run() now always return a TestResult instance. Previously it returned None if the test class or method was decorated with a skipping decorator. - Fix bugs in cleaning up classes and modules in unittest: - Functions registered with addModuleCleanup() were not called unless the user defines tearDownModule() in their test module. - Functions registered with addClassCleanup() were not called if tearDownClass is set to None. - Buffering in TestResult did not work with functions registered with addClassCleanup() and addModuleCleanup(). - Errors in functions registered with addClassCleanup() and addModuleCleanup() were not handled correctly in buffered and debug modes. - Errors in setUpModule() and functions registered with addModuleCleanup() were reported in wrong order. - And several lesser bugs. - Made email date parsing more robust against malformed input, namely a whitespace-only Date: header. Patch by Wouter Bolsterlee. - Fix a crash in the signal handler of the faulthandler module: no longer modify the reference count of frame objects. Patch by Victor Stinner. - Method stopTestRun() is now always called in pair with method startTestRun() for TestResult objects implicitly created in run(). Previously it was not called for test methods and classes decorated with a skipping decorator. - argparse.BooleanOptionalAction’s default value is no longer printed twice when used with argparse.ArgumentDefaultsHelpFormatter. - Upgrade bundled pip to 21.2.3 and setuptools to 57.4.0 - Fix the os.set_inheritable() function on FreeBSD 14 for file descriptor opened with the O_PATH flag: ignore the EBADF error on ioctl(), fallback on the fcntl() implementation. Patch by Victor Stinner. - The @functools.total_ordering() decorator now works with metaclasses. - sqlite3 user-defined functions and aggregators returning strings with embedded NUL characters are no longer truncated. Patch by Erlend E. Aasland. - Always show loop= arg deprecations in asyncio.gather() and asyncio.sleep() - Non-protocol subclasses of typing.Protocol ignore now the __init__ method inherited from protocol base classes. - The tokenize.tokenize() doesn’t incorrectly generate a NEWLINE token if the source doesn’t end with a new line character but the last line is a comment, as the function is already generating a NL token. Patch by Pablo Galindo - Fix http.client.HTTPSConnection fails to download >2GiB data. - rcompleter does not call getattr() on property objects to avoid the side-effect of evaluating the corresponding method. - weakref.proxy objects referencing non-iterators now raise TypeError rather than dereferencing the null tp_iternext slot and crashing. - The implementation of collections.abc.Set._hash() now matches that of frozenset.__hash__(). - Fixed issue in compileall.compile_file() when sys.stdout is redirected.

Patch by Dong-hee Na. - Fixes TypedDict to work with typing.get_type_hints() and postponed evaluation of annotations across modules. - Fix bug with pdb’s handling of import error due to a package which does not have a __main__ module - Fixed an exception thrown while parsing a malformed multipart email by email.message.EmailMessage. - pathlib.PureWindowsPath.is_reserved() now identifies a greater range of reserved filenames, including those with trailing spaces or colons. - Handle exceptions from parsing the arg of pdb’s run/restart command. - The sqlite3 context manager now performs a rollback (thus releasing the database lock) if commit failed. Patch by Luca Citi and Erlend E. Aasland. - Improved string handling for sqlite3 user-defined functions and aggregates: - It is now possible to pass strings with embedded null characters to UDFs - Conversion failures now correctly raise MemoryError - Patch by Erlend E. Aasland. - Handle RecursionError in TracebackException’s constructor, so that long exceptions chains are truncated instead of causing traceback formatting to fail. - Fix email.message.EmailMessage.set_content() when called with binary data and 7bit content transfer encoding. - The compresslevel and preset keyword arguments of tarfile.open() are now both documented and tested. - Fixed a Y2k38 bug in the compileall module where it would fail to compile files with a modification time after the year 2038. - Fix test___all__ on platforms lacking a shared memory implementation. - Pass multiprocessing BaseProxy argument manager_owned through AutoProxy. - email.utils.getaddresses() now accepts email.header.Header objects along with string values.

Now, there are nav links to attributes of TextWrap, which makes navigation much easier while minimizing duplication in the documentation. - Clarify that atexit uses equality comparisons internally. - Documentation of csv.Dialect is more descriptive. - Fix documentation for the return type of sysconfig.get_path(). - Add a “Security Considerations” index which links to standard library modules that have explicitly documented security considerations. - Remove the unqualified claim that tkinter is threadsafe. It has not been true for several years and likely never was. An explanation of what is true may be added later, after more discussion, and possibly after patching _tkinter.c, - Tests - Add calls of gc.collect() in tests to support PyPy. - Made tests relying on the _asyncio C extension module optional to allow running on alternative Python implementations. Patch by Serhiy Storchaka. - Fix auto history tests of test_readline: sometimes, the newline character is not written at the end, so don’t expect it in the output. - Add ability to wholesale silence DeprecationWarnings while running the regression test suite. - Notify users running test_decimal regression tests on macOS of potential harmless “malloc can’t allocate region” messages spewed by test_decimal. - Fixed floating point precision issue in turtle tests. - Regression tests, when run with -w, are now re-running only the affected test methods instead of re-running the entire test file. - Add test for nested queues when using multiprocessing shared objects AutoProxy[Queue] inside ListProxy and DictProxy * Fri Aug 27 2021 Matej Cepl <mcepl@suse.com> - Add decimal.patch to add building with --with-system-libmpdec option (bsc#1189356). * Thu Aug 26 2021 Andreas Schwab <schwab@suse.de> - test_faulthandler is still problematic under qemu linux-user emulation, disable it there - Reenable profileopt with qemu emulation, test_faulthandler is no longer run during profiling * Mon Aug 09 2021 Fusion Future <qydwhotmail@gmail.com> - Update to 3.9.6: * Security - bpo-44022 (bsc#1189241, CVE-2021-3737): http.client now avoids infinitely reading potential HTTP headers after a 100 Continue status response from the server. * Core and Builtins - bpo-44168: Fix error message in the parser involving keyword arguments with invalid expressions. Patch by Pablo Galindo - bpo-44114: Fix incorrect dictkeys_reversed and dictitems_reversed function signatures in C code, which broke webassembly builds. - bpo-44070: No longer eagerly makes import filenames absolute, except for extension modules, which was introduced in 3.9.5. - bpo-28146: Fix a confusing error message in str.format(). - bpo-11105: When compiling ast.AST objects with recursive references through compile(), the interpreter doesn’t crash anymore instead it raises a RecursionError. * Library - bpo-43972: When http.server.SimpleHTTPRequestHandler sends a 301 (Moved Permanently) for a directory path not ending with /, add a Content-Length: 0 header. This improves the behavior for certain clients. - bpo-43776: When subprocess.Popen args are provided as a string or as pathlib.Path, the Popen instance repr now shows the right thing. - bpo-43318: Fix a bug where pdb does not always echo cleared breakpoints. - bpo-43295: datetime.datetime.strptime() now raises ValueError instead of IndexError when matching 'z' with the %z format specifier. - bpo-37022: pdb now displays exceptions from repr() with its p and pp commands. * IDLE - bpo-33962: Move the indent space setting from the Font tab to the new Windows tab. Patch by Mark Roseman and Terry Jan Reedy. - bpo-40468: Split the settings dialog General tab into Windows and Shell/ED tabs. Move help sources, which extend the Help menu, to the Extensions tab. Make space for new options and shorten the dialog. The latter makes the dialog better fit small screens. - bpo-41611: Avoid uncaught exceptions in AutoCompleteWindow.winconfig_event(). - bpo-41611: Fix IDLE sometimes freezing upon tab-completion on macOS. * Tools/Demos - bpo-44074: Make patchcheck automatically detect the correct base branch name (previously it was hardcoded to ‘master’) - Upstreamed patches were removed: - bpo44426-complex-keyword-sphinx.patch - Refreshed patches: - subprocess-raise-timeout.patch * Mon Aug 02 2021 Matej Cepl <mcepl@suse.com> - Use versioned python-Sphinx to avoid dependency on other version of Python (bsc#1183858). * Sat Jun 19 2021 Matej Cepl <mcepl@suse.com> - Add bpo44426-complex-keyword-sphinx.patch allowing generating documentation with Sphinx 4 (bpo#44426). * Sat Jun 05 2021 Matej Cepl <mcepl@suse.com> - Revert previous skip over test_capi - Add skip-test_pyobject_freed_is_freed.patch to skip failing test on SLE-15. * Fri Jun 04 2021 Dirk Müller <dmueller@suse.com> - allow build with Sphinx >= 3.x * Wed Jun 02 2021 Dan Čermák <dcermak@suse.com> - Exclude test_capi on Leap (test fails there) * Fri May 21 2021 Matej Cepl <mcepl@suse.com> - Stop providing "python" symbol (bsc#1185588), which means python2 currently. * Wed May 05 2021 Matej Cepl <mcepl@suse.com> - Update to 3.9.5: * Security - bpo-43434: Creating a sqlite3.Connection object now also produces a sqlite3.connect auditing event.

Leading zeros are ambiguous and interpreted as octal notation by some libraries. For example the legacy function socket.inet_aton() treats leading zeros as octal notatation. glibc implementation of modern inet_pton() does not accept any leading zeros. For a while the ipaddress module used to accept ambiguous leading zeros. - bpo-43075 (CVE-2021-3733, bsc#1189287): Fix Regular Expression Denial of Service (ReDoS) vulnerability in urllib.request.AbstractBasicAuthHandler. The ReDoS-vulnerable regex has quadratic worst-case complexity and it allows cause a denial of service when identifying crafted invalid RFCs. This ReDoS issue is on the client side and needs remote attackers to control the HTTP server. - bpo-42800: Audit hooks are now fired for frame.f_code, traceback.tb_frame, and generator code/frame attribute access. * Core and Builtins - bpo-43105: Importlib now resolves relative paths when creating module spec objects from file locations. - bpo-42924: Fix bytearray repetition incorrectly copying data from the start of the buffer, even if the data is offset within the buffer (e.g. after reassigning a slice at the start of the bytearray to a shorter byte string). * Library - bpo-43993: Update bundled pip to 21.1.1. - bpo-43937: Fixed the turtle module working with non-default root window. - bpo-43930: Update bundled pip to 21.1 and setuptools to 56.0.0 - bpo-43920: OpenSSL 3.0.0: load_verify_locations() now returns a consistent error message when cadata contains no valid certificate. - bpo-43607: urllib can now convert Windows paths with \\?\ prefixes into URL paths. - bpo-43284: platform.win32_ver derives the windows version from sys.getwindowsversion().platform_version which in turn derives the version from kernel32.dll (which can be of a different version than Windows itself). Therefore change the platform.win32_ver to determine the version using the platform module’s _syscmd_ver private function to return an accurate version. - bpo-42248: [Enum] ensure exceptions raised in _missing__ are released - bpo-43799: OpenSSL 3.0.0: define OPENSSL_API_COMPAT 1.1.1 to suppress deprecation warnings.

Moreover, even source code of Python modules can contain sensitive data like passwords. Vulnerability reported by David Schwörer. - bpo#43285: ftplib no longer trusts the IP address value returned from the server in response to the PASV command by default. This prevents a malicious FTP server from using the response to probe IPv4 address and port combinations on the client network. Code that requires the former vulnerable behavior may set a trust_server_pasv_ipv4_address attribute on their ftplib.FTP instances to True to re-enable it. - bpo#43439: Add audit hooks for gc.get_objects(), gc.get_referrers() and gc.get_referents(). Patch by Pablo Galindo. - bpo#43660: Fix crash that happens when replacing sys.stderr with a callable that can remove the object while an exception is being printed. Patch by Pablo Galindo. - bpo#43555: Report the column offset for SyntaxError for invalid line continuation characters. Patch by Pablo Galindo. - bpo#43517: Fix misdetection of circular imports when using from pkg.mod import attr, which caused false positives in non-trivial multi-threaded code. - bpo#35883: Python no longer fails at startup with a fatal error if a command line argument contains an invalid Unicode character. The Py_DecodeLocale() function now escapes byte sequences which would be decoded as Unicode characters outside the [U+0000; U+10ffff] range. - bpo#43406: Fix a possible race condition where PyErr_CheckSignals tries to execute a non-Python signal handler. - bpo#42500: Improve handling of exceptions near recursion limit.

(bsc#1181324) * Mon Feb 08 2021 Matej Cepl <mcepl@suse.com> - Update to 3.9.1: Security bugs: - Prevented potential DoS attack via CPU and RAM exhaustion when processing malformed Apple Property List files in binary format. - The plistlib module no longer accepts entity declarations in XML plist files to avoid XML vulnerabilities. This should not affect users as entity declarations are not used in regular plist files. - Add volatile to the accumulator variable in hmac.compare_digest, making constant-time-defeating optimizations less likely. Core and Builtins - Allow assignment expressions in set literals and set comprehensions as per PEP 572. Patch by Pablo Galindo. - Fix a regression introduced by the new parser, where an unparenthesized walrus operator was not allowed within generator expressions. - types.GenericAlias objects can now be the targets of weakrefs. - Fixed a bug in the PEG parser that was causing crashes in debug mode. Now errors are checked in left-recursive rules to avoid cases where such errors do not get handled in time and appear as long-distance crashes in other places. - Fixed a possible crash in the PEG parser when checking for the ‘!=’ token in the barry_as_flufl rule. Patch by Pablo Galindo. - Fix handling of errors during creation of PyFunctionObject, which resulted in operations on uninitialized memory. Patch by Yonatan Goldschmidt. - Fix a bug in the parser, where a curly brace following a primary didn’t fail immediately. This led to invalid expressions like a {b} to throw a SyntaxError with a wrong offset, or invalid expressions ending with a curly brace like a { to not fail immediately in the REPL. - Fix possible buffer overflow in the new parser when checking for continuation lines. Patch by Pablo Galindo. - Run the parser two times. On the first run, disable all the rules that only generate better error messages to gain performance. If there’s a parse failure, run the parser a second time with those enabled. - Document the default implementation of object.__eq__. - Fix peephole optimizer misoptimize conditional jump + JUMP_IF_NOT_EXC_MATCH pair. - The garbage collector now tracks all user-defined classes. Patch by Brandt Bucher. - Fixed potential issues with removing not completely initialized module from sys.modules when import fails. - Star-unpacking is now allowed for with item’s targets in the PEG parser. - Fixed stack overflow in issubclass() and isinstance() when getting the __bases__ attribute leads to infinite recursion. - When loading a native module and a load failure occurs, prevent a possible UnicodeDecodeError when not running in a UTF-8 locale by decoding the load error message using the current locale’s encoding. - Correctly count control blocks in ‘except’ in compiler. Ensures that a syntax error, rather a fatal error, occurs for deeply nested, named exception handlers. Library - types.GenericAlias will now raise a TypeError when attempting to initialize with a keyword argument. Previously, this would cause the interpreter to crash if the interpreter was compiled with debug symbols. This does not affect interpreters compiled for release. Patch by Ken Jin. - CGIHTTPRequestHandler.run_cgi() HTTP_ACCEPT improperly parsed. Replace the special purpose getallmatchingheaders with generic get_all method and add relevant tests. - inspect.findsource() now raises OSError instead of IndexError when co_lineno of a code object is greater than the file length. This can happen, for example, when a file is edited after it was imported. PR by Irit Katriel. - Fix handling of trailing comments by inspect.getsource(). - ChainMap.__iter__ no longer calls __getitem__ on underlying maps - TracebackException no longer holds a reference to the exception’s traceback object. Consequently, instances of TracebackException for equivalent but non-equal exceptions now compare as equal. - We fixed an issue in pickle.whichmodule in which importing multiprocessing could change the how pickle identifies which module an object belongs to, potentially breaking the unpickling of those objects. - Clarify the error message for asyncio.IncompleteReadError when expected is None. - Extracting a symlink from a tarball should succeed and overwrite the symlink if it already exists. The fix is to remove the existing file or symlink before extraction. Based on patch by Chris AtLee, Jeffrey Kintscher, and Senthil Kumaran. - Fixed tkinter.ttk.Style.map(). The function accepts now the representation of the default state as empty sequence (as returned by Style.map()).
