Summary

Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems.
The following packages have been upgraded to a later upstream version: python39 (3.9.16).

* python: int() type in PyLong_FromString() does not limit amount of digits converting text to int leading to DoS (CVE-2020-10735)
* python: open redirection vulnerability in lib/http/server.py may lead to information disclosure (CVE-2021-28861)
* python: CPU denial of service via inefficient IDNA decoder (CVE-2022-45061)
