Python Insider: Python 3.13.4, 3.12.11, 3.11.13, 3.10.18 and 3.9.23 are now available

Multiple Python versions (3.13.4, 3.12.11, 3.11.13, 3.10.18, and 3.9.23) have been released simultaneously to address critical security vulnerabilities. The releases fix multiple CVEs in the tarfile module that allowed extraction filters to be bypassed through crafted symlinks and hard links, a use-after-free bug in the unicode-escape decoder, and IPv6 address processing issues that could cause denial-of-service. Python 3.13.4 includes over 300 additional bugfixes and improvements beyond the security patches.
