Summary: Security update for python39
Type: security
Severity: important
References: 1192249,1198511,CVE-2015-20107
This update for python39 fixes the following issues:
- CVE-2015-20107: avoid command injection in the mailcap module (bsc#1198511).
- Update to 3.9.13:
- Core and Builtins
- gh-92311: Fixed a bug where setting frame.f_lineno to jump
over a list comprehension could misbehave or crash.
- gh-92112: Fix crash triggered by an evil custom mro() on
a metaclass.
- gh-92036: Fix a crash in subinterpreters related to the
garbage collector. 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. Previously an internal RuntimeError was
raised.
- gh-91676: Fix unittest.IsolatedAsyncioTestCase to shutdown
the per test event loop executor before returning from its
run method so that a not yet stopped or garbage collected
executor state does not persist beyond the test.
- gh-90568: Parsing \N escapes of Unicode Named Character
Sequences in a regular expression raises now re.error
instead of TypeError.
- gh-91595: Fix the comparison of character and integer
inside Tools.gdb.libpython.write_repr(). 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 Marek Suscak.
- bpo-27929: Fix asyncio.loop.sock_connect() to only resolve
names for socket.AF_INET or socket.AF_INET6 families.
Resolution may not make sense for other families, like
socket.AF_BLUETOOTH and socket.AF_UNIX.
- bpo-43323: Fix errors in the email module if the charset
itself contains undecodable/unencodable characters.
- bpo-46787: Fix concurrent.futures.ProcessPoolExecutor
exception memory leak
- bpo-46415: Fix ipaddress.ip_{address,interface,network}
raising TypeError instead of ValueError if given invalid
tuple as address parameter.
- bpo-44911: IsolatedAsyncioTestCase will no longer throw an
exception while cancelling leaked tasks. Patch by Bar
Harel.
- bpo-44493: Add missing terminated NUL in sockaddr_un's
length
- This was potentially observable when using non-abstract
AF_UNIX datagram sockets to processes written in another
programming language.
- bpo-42627: Fix incorrect parsing of Windows registry proxy
settings
- bpo-36073: Raise ProgrammingError instead of segfaulting on
recursive usage of cursors in sqlite3 converters. Patch by
Sergey Fedoseev.

version 2.4.4.
- bpo-46962: All docstrings in code snippets are now wrapped
into PyDoc_STR() to follow the guideline of PEP 7's
Documentation Strings paragraph. Patch by Oleg Iarygin.
- bpo-26792: Improve the docstrings of runpy.run_module() and
runpy.run_path(). Original patch by Andrew Brezovsky.

Types: Tutorial about the ob_base field and the macros used
to access its contents.
- bpo-42340: Document that in some circumstances
KeyboardInterrupt may cause the code to enter an
inconsistent state. Provided a sample workaround to avoid
it if needed.
- bpo-41233: Link the errnos referenced in
Doc/library/exceptions.rst to their respective section in
Doc/library/errno.rst, and vice versa. Previously this was
only done for EINTR and InterruptedError. Patch by Yan
'yyyyyyyan' Orestes.
- bpo-38056: Overhaul the Error Handlers documentation in
codecs.
- bpo-13553: Document tkinter.Tk args.
- Tests
- gh-91607: Fix test_concurrent_futures to test the correct
multiprocessing start method context in several cases where
the test logic mixed this up.

in faulthandler to avoid compilation problems in systems
where this header doesn't exist. Patch by Pablo Galindo
- bpo-47101: hashlib.algorithms_available now lists only
algorithms that are provided by activated crypto providers on
OpenSSL 3.0. Legacy algorithms are not listed unless the
legacy provider has been loaded into the default OSSL
context.
- bpo-23691: Protect the re.finditer() iterator from
re-entering.
- bpo-42369: Fix thread safety of zipfile._SharedFile.tell() to
avoid a 'zipfile.BadZipFile: Bad CRC-32 for file' exception
when reading a ZipFile from multiple threads.
- bpo-38256: Fix binascii.crc32() when it is compiled to use
zlib'c crc32 to work properly on inputs 4+GiB in length
instead of returning the wrong result. The workaround prior
to this was to always feed the function data in increments
smaller than 4GiB or to just call the zlib module function.
- bpo-39394: A warning about inline flags not at the start of
the regular expression now contains the position of the flag.

- bpo-47022: The asynchat, asyncore and smtpd modules have been
deprecated since at least Python 3.6. Their documentation has
now been updated to note they will removed in Python 3.12
(PEP 594).
- bpo-46421: Fix a unittest issue where if the command was
invoked as python -m unittest and the filename(s) began with
a dot (.), a ValueError is returned.
- bpo-40296: Fix supporting generic aliases in pydoc.
- bpo-14156: argparse.FileType now supports an argument of '-';
in binary mode, returning the .buffer attribute of
sys.stdin/sys.stdout as appropriate. Modes including 'x' and
'a' are treated equivalently to 'w' when argument is '-'.
Patch contributed by Josh Rosenberg
- Update to 3.9.11:
- bpo-46852: Rename the private undocumented
float.__set_format__() method to float.__setformat__() to fix

Patch by Jelle Zijlstra.
- bpo-40479: Add a missing call to va_end() in
Modules/_hashopenssl.c.
- bpo-46615: When iterating over sets internally in
setobject.c, acquire strong references to the resulting items
from the set. This prevents crashes in corner-cases of
various set operations where the set gets mutated.
- bpo-43721: Fix docstrings of getter, setter, and deleter to
clarify that they create a new copy of the property.
- bpo-46503: Fix an assert when parsing some invalid N escape
sequences in f-strings.
- bpo-46417: Fix a race condition on setting a type __bases__
attribute: the internal function add_subclass() now gets the
PyTypeObject.tp_subclasses member after calling
PyWeakref_NewRef() which can trigger a garbage collection
which can indirectly modify PyTypeObject.tp_subclasses. Patch
by Victor Stinner.
- bpo-46383: Fix invalid signature of _zoneinfo's module_free
function to resolve a crash on wasm32-emscripten platform.

22.0.4)
- bpo-46968: faulthandler: On Linux 5.14 and newer, dynamically
determine size of signal handler stack size CPython allocates
using getauxval(AT_MINSIGSTKSZ). This changes allows for
Python extension's request to Linux kernel to use AMX_TILE
instruction set on Sapphire Rapids Xeon processor to succeed,
unblocking use of the ISA in frameworks.

- bpo-46756: Fix a bug in
urllib.request.HTTPPasswordMgr.find_user_password() and
urllib.request.HTTPPasswordMgrWithPriorAuth.is_authenticated()
which allowed to bypass authorization. For example, access to
URI example.org/foobar was allowed if the user was authorized
for URI example.org/foo.
- bpo-45863: When the tarfile module creates a pax format
archive, it will put an integer representation of timestamps
in the ustar header (if possible) for the benefit of older
unarchivers, in addition to the existing full-precision
timestamps in the pax extended header.
- bpo-46672: Fix NameError in asyncio.gather() when initial
type check fails.
- bpo-45948: Fixed a discrepancy in the C implementation of the
xml.etree.ElementTree module. Now, instantiating an
xml.etree.ElementTree.XMLParser with a target=None keyword
provides a default xml.etree.ElementTree.TreeBuilder target
as the Python implementation does.

allowed a cryptic AttributeError to escape.
- bpo-46474: In importlib.metadata.EntryPoint.pattern, avoid
potential REDoS by limiting ambiguity in consecutive
whitespace.
- bpo-46469: asyncio generic classes now return
types.GenericAlias in __class_getitem__ instead of the same
class.

missing, for example when run with pregenerated optimized
.pyc files.
- bpo-46333: The __eq__() and __hash__() methods of
typing.ForwardRef now honor the module parameter of
typing.ForwardRef. Forward references from different modules
are now differentiated.

it to fail on some subclasses of classes with
a __text_signature__ referencing module globals. Patch by
Weipeng Hong.
- bpo-21987: Fix an issue with tarfile.TarFile.getmember()
getting a directory name with a trailing slash.

protocol, the file length may be wrong.
- bpo-45703: When a namespace package is imported before
another module from the same namespace is created/installed
in a different sys.path location while the program is
running, calling the importlib.invalidate_caches() function
will now also guarantee the new module is noticed.
- bpo-24959: Fix bug where unittest sometimes drops frames from
tracebacks of exceptions raised in tests.
- bpo-46463: Fixes escape4chm.py script used when building the
CHM documentation file
- bpo-46913: Fix test_faulthandler.test_sigfpe() if Python is

modify these tests to use support.infinite_recursion(). Patch
by Victor Stinner.
- bpo-13886: Skip test_builtin PTY tests on non-ASCII
characters if the readline module is loaded. The readline
module changes input() behavior, but test_builtin is not
intented to test the readline module. Patch by Victor
Stinner.
- bpo-38472: Fix GCC detection in setup.py when
cross-compiling. The C compiler is now run with LC_ALL=C.
Previously, the detection failed with a German locale.
- bpo-46513: configure no longer uses AC_C_CHAR_UNSIGNED macro
and pyconfig.h no longer defines reserved symbol
__CHAR_UNSIGNED__.
- bpo-45925: Update Windows installer to use SQLite 3.37.2.

menu, 'Close' and 'Exit' are now 'Close Window' (the current
one) and 'Exit' is now 'Exit IDLE' (by closing all windows).
In Shell, 'quit()' and 'exit()' mean 'close Shell'. If there
are no other windows, this also exits IDLE.
