and with the new:option:`--help-all`.

* Converting between:class:`int` and:class:`str` in bases other than 2

(binary), 4, 8 (octal), 16 (hexadecimal), or 32 such as base 10 (decimal)

now raises a:exc:`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 limit can be configured or disabled by environment variable, command

line flag, or:mod:`sys` APIs. See the:ref:`integer string conversion

length limitation <int_max_str_digits>` documentation. The default limit

is 4300 digits in string form.
