--------------------------------------------------------------------------------

Name        : python3.9
Product     : Fedora 40
Version     : 3.9.21
Release     : 1.fc40
URL         : https://www.python.org/
Summary     : Version 3.9 of the Python interpreter
Description :
Python 3.9 package for developers.

This package exists to allow developers to test their code against an older
version of Python. This is not a full Python stack and if you wish to run
your applications with Python 3.9, see other distributions
that support it, such as CentOS or RHEL or older Fedora releases.

--------------------------------------------------------------------------------
Update Information:

Python 3.9.21 security release.
Security content in this release
gh-122792: Changed IPv4-mapped ipaddress.IPv6Address to consistently use the
mapped IPv4 address value for deciding properties. Properties which have their
behavior fixed are is_multicast, is_reserved, is_link_local, is_global, and
is_unspecified.
CVE-2024-9287: gh-124651: Properly quote template strings in venv activation
scripts.
gh-103848: Added checks to ensure that [ bracketed ] hosts found by
urllib.parse.urlsplit() are of IPv6 or IPvFuture format.
gh-95588: Clarified the conflicting advice given in the ast documentation about
ast.literal_eval() being "safe" for use on untrusted input while at the same
time warning that it can crash the process. The latter statement is true and is
deemed unfixable without a large amount of work unsuitable for a bugfix. So we
keep the warning and no longer claim that literal_eval is safe.
