An update that solves two vulnerabilities can now be installed.
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 (originally filed as CVE-2022-37460, later withdrawn)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.
