Important: python39:3.9 security update

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. Security Fix(es): * python: Invalid value for OpenSSL API may cause Buffer over-read when NPN is used (CVE-2024-5642) * python: Virtual environment (venv) activation scripts don't quote paths (CVE-2024-9287) * python: Improper validation of IPv6 and IPvFuture addresses (CVE-2024-11168) * python: cpython: URL parser allowed square brackets in domain names (CVE-2025-0938) * cpython: python: CPython DecodeError Handling Vulnerability (CVE-2025-4516) * cpython: Tarfile extracts filtered members when errorlevel=0 (CVE-2025-4435) * cpython: python: Extraction filter bypass for linking outside extraction directory (CVE-2025-4330) * python: cpython: Arbitrary writes via tarfile realpath overflow (CVE-2025-4517) * cpython: python: Bypassing extraction filter to create symlinks to arbitrary targets outside extraction directory (CVE-2025-4138) * cpython: Python HTMLParser quadratic complexity (CVE-2025-6069) * cpython: python: Python zipfile End of Central Directory (EOCD) Locator record offset not checked (CVE-2025-8291) * python: Quadratic complexity in os.path.expandvars() with user-controlled template (CVE-2025-6075) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
