[3.7] gh-95778: CVE-2020-10735: Prevent DoS by very large int() (GH-96504)

2022-09-06T05:24:36+00:00

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. This is a mitigation for CVE-2020-10735
(https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10735).

This new limit can be configured or disabled by environment variable, command
line flag, or :mod:`sys` APIs. See the `Integer String Conversion Length
Limitation` documentation.  The default limit is 4300
digits in string form.

Patch by Gregory P. Smith [Google] and Christian Heimes [Red Hat] with feedback
from Victor Stinner, Thomas Wouters, Steve Dower, Ned Deily, and Mark Dickinson.

bpo-36356: pymain_free() calls _PyRuntime_Finalize() (GH-12436)

2019-03-19T14:08:17+00:00

Ensure that _PyRuntime_Finalize() is always call. This change fix a
few memory leaks when running "python3 -V".

bpo-32604: Expose the subinterpreters C-API in a "private" stdlib module. (gh-1748)

2018-01-30T01:23:44+00:00

The module is primarily intended for internal use in the test suite.  Building the module under Windows will come in a follow-up PR.

bpo-31901: atexit callbacks should be run at subinterpreter shutdown (#4611)

Change atexit behavior and PEP-489 multiphase init support.

bpo-32030: Rewrite _PyMainInterpreterConfig (#4854)

2017-12-14T01:20:52+00:00

_PyMainInterpreterConfig now contains Python objects, whereas
_PyCoreConfig contains wchar_t* strings.

Core config:

* Rename _PyMainInterpreterConfig_ReadEnv() to _PyCoreConfig_ReadEnv()
* Move 3 strings from _PyMainInterpreterConfig to _PyCoreConfig:
  module_search_path_env, home, program_name.
* Add _PyCoreConfig_Clear()
* _PyPathConfig_Calculate() now takes core config rather than main
  config
* _PyMainInterpreterConfig_Read() now requires also a core config

Main config:

* Add _PyMainInterpreterConfig.module_search_path: sys.path list
* Add _PyMainInterpreterConfig.argv: sys.argv list
* _PyMainInterpreterConfig_Read() now computes module_search_path

bpo-32030: Simplify _PyCoreConfig_INIT macro (#4728)

2017-12-05T14:12:41+00:00

* Simplify _PyCoreConfig_INIT, _PyMainInterpreterConfig_INIT,
  _PyPathConfig_INIT macros: no need to set fields to 0/NULL, it's
  redundant (the C language sets them to 0/NULL for us).
* Fix typo: pymain_run_statup() => pymain_run_startup()
* Remove a few XXX/TODO
