- Update to 3.10.9:
- python -m http.server no longer allows terminal
control characters sent within a garbage request to be
printed to the stderr server lo This is done by changing
the http.server BaseHTTPRequestHandler .log_message method
to replace control characters with a \xHH hex escape before
printin
- Avoid publishing list of active per-interpreter
audit hooks via the gc module
- The IDNA codec decoder used on DNS hostnames by
socket or asyncio related name resolution functions no
longer involves a quadratic algorithm. This prevents a
potential CPU denial of service if an out-of-spec excessive
length hostname involving bidirectional characters were
decoded. Some protocols such as urllib http 3xx redirects
potentially allow for an attacker to supply such a name.
- Update bundled libexpat to 2.5.0
- Port XKCP’s fix for the buffer overflows in SHA-3
(CVE-2022-37454).
- On Linux the multiprocessing module returns
to using filesystem backed unix domain sockets for
communication with the forkserver process instead of the
Linux abstract socket namespace. Only code that chooses
to use the “forkserver” start method is affected Abstract
sockets have no permissions and could allow any user
on the system in the same network namespace (often the
whole system) to inject code into the multiprocessing
forkserver process. This was a potential privilege
escalation. Filesystem based socket permissions restrict
this to the forkserver process user as was the default in

- 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filed as CVE-2022-37460, later withdrawn)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.

- Update to 3.10.7:
- Fix for CVE-2020-10735 (bsc#1203125) Converting between int
and str in bases other than 2 (binary), 4, 8 (octal), 16
(hexadecimal), or 32 such as base 10 (decimal) now raises
a ValueError if the number of digits in string form is above
a limit to avoid potential denial of service attacks due to
the algorithmic complexity.
- Other bug fixes:
- Fixed a bug that caused _PyCode_GetExtra to return garbage
for negative indexes.
- Fix format string in _PyPegen_raise_error_known_location
that can lead to memory corruption on some 64bit systems.
The function was building a tuple with i (int) instead of
n (Py_ssize_t) for Py_ssize_t arguments.
- Fix misleading contents of error message when converting an
all-whitespace string to float.
- coroutine.throw() now properly initializes the frame.f_back
when resuming a stack of coroutines. This allows e.g.
traceback.print_stack() to work correctly when an exception
(such as CancelledError) is thrown into a coroutine.
- ast.parse() will no longer parse function definitions with
positional-only params when passed feature_version less
than (3, 8).
- Correct conversion of numbers.Rational’s to float.
- Fix a performance regression in logging
TimedRotatingFileHandler. Only check for special files when
the rollover time has passed.
- Fix unused localName parameter in the Attr class in
xml.dom.minidom.
- Update bundled pip to 22.2.2.
