An update that fixes two vulnerabilities is now available.
Description:
This update for python310 fixes the following issues:
Security fixes:
- CVE-2022-42919: Fixed local privilege escalation via the multiprocessing
forkserver start method (bsc#1204886).
- CVE-2022-45061: Fixed a quadratic IDNA decoding time (bsc#1205244).
Other fixes:
- allow building of documentation with the latest Sphinx 5.3.0
(gh#python/cpython#98366).
- Update to 3.10.8:
- 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later withdrawn)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.
- 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).
- os.sched_yield() now release the GIL while calling sched_yield(2).
- Bugfix: PyFunction_GetAnnotations() should return a borrowed
reference. It was returning a new reference.
- Fixed a missing incref/decref pair in Exception.__setstate__().
- Fix overly-broad source position information for chained comparisons
used as branching conditions.
- Fix undefined behaviour in _testcapimodule.c.
- At Python exit, sometimes a thread holding the GIL can wait forever
for a thread (usually a daemon thread) which requested to drop the
GIL, whereas the thread already exited. To fix the race condition, the
thread which requested the GIL drop now resets its request before
exiting.
- Fix a possible assertion failure, fatal error, or SystemError if a
line tracing event raises an exception while opcode tracing is enabled.
- Fix undefined behaviour in C code of null pointer arithmetic.
- Do not expose KeyWrapper in _functools.
- When loading a file with invalid UTF-8 inside a multi-line string, a
correct SyntaxError is emitted.
- Disable incorrect pickling of the C implemented classmethod
descriptors.
- Fix AttributeError missing name and obj attributes in .
object.__getattribute__() bpo-42316: Document some places . where an
assignment expression needs parentheses .
- Wrap network errors consistently in urllib FTP support, so the test
suite doesn’t fail when a network is available but the public
internet is not reachable.
- Fixes AttributeError when subprocess.check_output() is used with
argument input=None and either of the arguments encoding
or errors are used.
- Avoid spurious tracebacks from asyncio when default executor cleanup
is delayed until after the event loop is closed (e.g. as the result of
a keyboard interrupt).
- Avoid a crash in the C version of
asyncio.Future.remove_done_callback() when an evil argument is passed.
- Remove tokenize.NL check from tabnanny.
- Make Semaphore run faster.
- Fix generation of the default name of tkinter.Checkbutton. Previously,
checkbuttons in different parent widgets could have the same short
name and share the same state if arguments “name†and
“variable†are not specified. Now they are globally unique.
- Update bundled libexpat to 2.4.9
- Fix race condition in asyncio where process_exited() called before the
pipe_data_received() leading to inconsistent
output.
- Fixed check in multiprocessing.resource_tracker that guarantees that
the length of a write to a pipe is not greater than PIPE_BUF.
- Corrected type annotation for dataclass attribute
pstats.FunctionProfile.ncalls to be str.
- Fix the faulthandler implementation of faulthandler.register(signal,
chain=True) if the sigaction() function is not available: don’t call
the previous signal handler if it’s NULL.
- In inspect, fix overeager replacement of “typing.†in formatting
annotations.
- Fix asyncio.streams.StreamReaderProtocol to keep a strong reference to
the created task, so that it’s not garbage collected
- Fix handling compiler warnings (SyntaxWarning and DeprecationWarning)
in codeop.compile_command() when checking for incomplete input.
Previously it emitted warnings and raised a SyntaxError. Now it always
returns None for incomplete input without emitting any warnings.
- Fixed flickering of the turtle window when the tracer is turned off.
- Allow asyncio.StreamWriter.drain() to be awaited concurrently by
multiple tasks.
- Fix broken asyncio.Semaphore when acquire is cancelled.
- Fix ast.unparse() when ImportFrom.level is None
- Improve performance of urllib.request.getproxies_environment when
there are many environment variables
- Fix ! in c domain ref target syntax via a conf.py patch, so it works
as intended to disable ref target resolution.
- Clarified the conflicting advice given in the ast documentation about
ast.literal_eval() being “safe†for use
on untrusted input while at the same time warning that it can crash
the process. The latter statement is true and is deemed unfixable
without a large amount of work unsuitable for a bugfix. So we keep
the warning and no longer claim that literal_eval is safe.
- Update tutorial introduction output to use 3.10+ SyntaxError invalid
range.
