python3: upgrade to 3.8.17
License-Update: update year to 2023
30afa75ad8
Release Notes for 3.8.15:
Security content in this release
CVE-2022-40674: bundled libexpat was upgraded from 2.4.7 to 2.4.9 which
fixes a heap use-after-free vulnerability in function doContent
gh-97616: a fix for a possible buffer overflow in list *= int
gh-97612: a fix for possible shell injection in the example script
get-remote-certificate.py (this issue originally had a CVE assigned to
it, which its author withdrew)
gh-96577: a fix for a potential buffer overrun in msilib
https://www.python.org/downloads/release/python-3815/
Release Notes for 3.8.16:
Security content in this release
gh-98739: Updated bundled libexpat to 2.5.0 to fix CVE-2022-43680 (heap
use-after-free).
gh-98517: Port XKCP’s fix for the buffer overflows in SHA-3 to fix
CVE-2022-37454.
gh-98433: The IDNA codec decoder used on DNS hostnames by socket or
asyncio related name resolution functions no longer involves a quadratic
algorithm to fix CVE-2022-45061. 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.
gh-68966: The deprecated mailcap module now refuses to inject unsafe
text (filenames, MIME types, parameters) into shell commands to address
CVE-2015-20107. 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).
gh-100001: python -m http.server no longer allows terminal control
characters sent within a garbage request to be printed to the stderr
server log.
gh-87604: Avoid publishing list of active per-interpreter audit hooks
via the gc module.

Release Notes for 3.8.17:
Security content in this release
gh-103142: The version of OpenSSL used in Windows and Mac installers has
been upgraded to 1.1.1u to address CVE-2023-2650, CVE-2023-0465,
CVE-2023-0466, CVE-2023-0464, as well as CVE-2023-0286, CVE-2022-4303,
and CVE-2022-4303 fixed previously in 1.1.1t (gh-101727).
gh-102153: urllib.parse.urlsplit() now strips leading C0 control and
space characters following the specification for URLs defined by WHATWG
in response to CVE-2023-24329.
gh-99889: Fixed a security in flaw in uu.decode() that could allow for
directory traversal based on the input if no out_file was specified.
gh-104049: Do not expose the local on-disk location in directory indexes
produced by http.client.SimpleHTTPRequestHandler.
gh-103935: trace.__main__ now uses io.open_code() for files to be
executed instead of raw open().
gh-101283: subprocess.Popen now uses a safer approach to find cmd.exe
when launching with shell=True.
gh-102953: The extraction methods in tarfile, and
shutil.unpack_archive(), have a new filter argument that allows limiting
tar features than may be surprising or dangerous, such as creating files
outside the destination directory. See Extraction filters for details.
