bpo-46794: Bump up the libexpat version into 2.4.6
bpo-46985: Upgrade pip wheel bundled with ensurepip (pip 22.0.4)
bpo-46932: Update bundled libexpat to 2.4.7
bpo-46811: Make test suite support Expat >=2.4.5
bpo-46784: Fix libexpat symbols collisions with user
dynamically loaded or statically linked libexpat in embedded
Python.
bpo-46400: expat: Update libexpat from 2.4.1 to 2.4.4
bpo-46474: In importlib.metadata.EntryPoint.pattern, avoid
potential REDoS by limiting ambiguity in consecutive
whitespace.
bpo-44849: 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.
bpo-41028: Language and version switchers, previously
maintained in every cpython branches, are now handled by
docsbuild-script.
bpo-45195: Fix test_readline.test_nonascii(): sometimes, the
newline character is not written at the end, so don’t
expect it in the output.
bpo-44949: 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.
bpo-45405: Prevent internal configure error when running
configure with recent versions of clang.
- Remove upstreamed patches:
- support-expat-245.patch
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:Factory/python38?expand=0&rev=85
- Update to 3.8.12
* Complete list of changes is available at
https://docs.python.org/release/3.8.12/whatsnew/changelog.html
* Security
- bpo-42278: Replaced usage of tempfile.mktemp() with
TemporaryDirectory to avoid a potential race condition.
- bpo-44394: Update the vendored copy of libexpat to 2.4.1
(from 2.2.8) to get the fix for the CVE-2013-0340 “Billion
Laughs” vulnerability. This copy is most used on Windows and
macOS.
- bpo-43124: Made the internal putcmd function in smtplib
sanitize input for presence of \r and \n characters to avoid
(unlikely) command injection.
- bpo-36384: ipaddress module no longer accepts any leading
zeros in IPv4 address strings. 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 notation. glibc implementation of modern
inet_pton() does not accept any leading zeros. For a while
the ipaddress module used to accept ambiguous leading zeros.
- Refreshed patch:
* decimal-3.8.patch
OBS-URL: https://build.opensuse.org/request/show/915148
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:Factory/python38?expand=0&rev=80
- Update to 3.8.11
* Security
- bpo-44022 (boo#1189241): mod:http.client now avoids
infinitely reading potential HTTP headers after a 100
Continue status response from the server.
- bpo-43882: The presence of newline or tab characters in parts
of a URL could allow some forms of attacks.
Following the controlling specification for URLs defined by
WHATWG urllib.parse() now removes ASCII newlines and tabs
from URLs, preventing such attacks.
- bpo-42800: Audit hooks are now fired for frame.f_code,
traceback.tb_frame, and generator code/frame attribute
access.
* Core and Builtins
- bpo-44070: No longer eagerly makes import filenames absolute,
except for extension modules, which was introduced in 3.8.10.
* Library
- bpo-44061: Fix regression in previous release when calling
pkgutil.iter_modules() with a list of pathlib.Path objects

- Security
- bpo-43434: Creating a sqlite3.Connection object now also
produces a sqlite3.connect auditing event. Previously this
event was only produced by sqlite3.connect() calls. Patch
by Erlend E. Aasland.
- bpo-43472: Ensures interpreter-level audit hooks receive
the cpython.PyInterpreterState_New event when called
through the _xxsubinterpreters module.
- bpo-43075: 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.
- 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
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:Factory/python38?expand=0&rev=66
- bpo#42988 (bsc#1183374) CVE-2021-3426: Remove the getfile
feature of the pydoc module which could be abused to read
arbitrary files on the disk (directory traversal
vulnerability). 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-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-35930: Raising an exception raised in a “future” instance
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:Factory/python38?expand=0&rev=62
- bpo#42938 (bsc#1181126): Avoid static buffers when computing
the repr of ctypes.c_double and ctypes.c_longdouble
values. This issue was assigned CVE-2021-3177.
- bpo#42967 (bso#1182379): Fix web cache poisoning
vulnerability by defaulting the query args separator to &,
and allowing the user to choose a custom separator. This
issue was assigned CVE-2021-23336.
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:Factory/python38?expand=0&rev=53
- Last try before this results in an editwar:
* remove importlib_resources and importlib-metadata
provides/obsoletes
* import importlib_resources is not the same as
import importlib.resources, same for metadata
* The backport packages from PyPI needed for older flavors are
specified as such for setuptools or in pyproject.toml. If a
package requires them they typically add them with a python
version qualifier and the packages have their own version
numbers.

- Update to version 3.8.5:
- bpo-39603: Prevent http header injection by rejecting control characters in http.client.putrequest(…).
- bpo-41295: a regression in CPython 3.8.4 where defining “__setattr__” in a multi-inheritance setup and calling up the hierarchy chain could fail if builtins/extension types were involved in the base types.
- bpo-41288: Unpickling invalid NEWOBJ_EX opcode with the C implementation raises now UnpicklingError instead of crashing.
- bpo-39017: Avoid infinite loop when reading specially crafted TAR files using the tarfile module (CVE-2019-20907).
- bpo-37703: Updated Documentation to comprehensively elaborate on the behaviour of gather.cancel()
- bpo-41302: Enable building Python 3.8 with libmpdec-2.5.0 to ease maintenance for Linux distributions. Patch by Felix Yan.
