Advisory ID: SUSE-SU-2022:2174-1
Released:    Fri Jun 24 11:34:17 2022
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 G?ry 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.
  - Documentation
    - gh-91888: Add a new gh role to the documentation to link to
      GitHub issues.
    - gh-91783: Document security issues concerning the use of
      the function shutil.unpack_archive()
    - gh-91547: Remove 'Undocumented modules' page.
    - bpo-44347: Clarify the meaning of dirs_exist_ok, a kwarg of
      shutil.copytree().

      os.path to remove warnings that became irrelevant after the
      implementations of PEP 383 and PEP 529.
    - bpo-47138: Pin Jinja to a version compatible with Sphinx
      version 2.4.4.
    - bpo-46962: All docstrings in code snippets are now wrapped

      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.
    - bpo-45790: Adjust inaccurate phrasing in Defining Extension
      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.

    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

  - bpo-38256: Fix binascii.crc32() when it is compiled to use
    zlib'c crc32 to work properly on inputs 4+GiB in length

    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-47061: Deprecate the various modules listed by PEP 594:

    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
    a typo introduced in Python 3.7. The method is only used by
    test_float. Patch by Victor Stinner.
  - bpo-46794: Bump up the libexpat version into 2.4.6
  - bpo-46762: Fix an assert failure in debug builds when a '<',
    '>', or '=' is the last character in an f-string that's
    missing a closing right brace.
  - bpo-46732: Correct the docstring for the __bool__() method.
    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.
  - bpo-43253: Fix a crash when closing transports where the
    underlying socket handle is already invalid on the Proactor
    event loop.
  - bpo-47004: Apply bugfixes from importlib_metadata 4.11.3,

    match objects and not the extras strings.
  - bpo-46985: Upgrade pip wheel bundled with ensurepip (pip
    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-46955: Expose asyncio.base_events.Server as
    asyncio.Server. Patch by Stefan Zabka.
  - bpo-46932: Update bundled libexpat to 2.4.7
  - bpo-25707: Fixed a file leak in

    shared folders when running from the guest operating-system.
  - 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.
  - bpo-46591: Make the IDLE doc URL on the About IDLE dialog
    clickable.
  - bpo-46400: expat: Update libexpat from 2.4.1 to 2.4.4

    typing.ClassVar. Patch by Gregory Beauregard.
  - bpo-46436: Fix command-line option -d/--directory in module
    http.server which is ignored when combined with command-line
    option --cgi. Patch by G?ry Ogam.
  - bpo-41403: Make mock.patch() raise a TypeError with
    a relevant error message on invalid arg. Previously it
    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.
  - bpo-46434: pdb now gracefully handles help when __doc__ is
    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.
  - bpo-43118: Fix a bug in inspect.signature() that was causing
    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.
  - bpo-20392: Fix inconsistency with uppercase file extensions

    when the input data is an object that supports the buffer
    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

    Stinner.
  - bpo-46708: Prevent default asyncio event loop policy
    modification warning after test_asyncio execution.
  - bpo-46616: Ensures test_importlib.test_windows cleans up
    registry keys after completion.

    Python built in debug mode: limit the recursion limit. Patch
    by Victor Stinner.
  - bpo-46576: test_peg_generator now disables compiler
    optimization when testing compilation of its own C extensions
    to significantly speed up the testing on non-debug builds of
    CPython.
  - bpo-46542: Fix test_json tests checking for RecursionError:
    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.

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 G?ry Ogam.

- gh-91910: Add missing f prefix to f-strings in error

messages from the multiprocessing and asyncio modules.

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.

inside Tools.gdb.libpython.write_repr(). Patch by Yu Liu.

- gh-90622: Worker processes for

concurrent.futures.ProcessPoolExecutor are no longer

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

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

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.
