Multiple vulnerabilities have been discovered in Microsoft products, the most severe of which could allow for remote code execution in the context of the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
This is the sixth maintenance release of Python 3.12
Python 3.12 is the newest major release of the Python programming language, and it contains many new features and optimizations. 3.12.6 is the latest maintenance release, containing about 90 bugfixes, build improvements and documentation changes since 3.12.5. This is an expedited release to address the following security issues:
gh-123067: Fix quadratic complexity in parsing “-quoted cookie values with backslashes by http.cookies. Fixes CVE-2024-7592. gh-121285: Remove backtracking from tarfile header parsing for hdrcharset, PAX, and GNU sparse headers. That’s CVE-2024-6232. gh-102988: email.utils.getaddresses() and email.utils.parseaddr() now return (”, ”) 2-tuples in more situations where invalid email addresses are encountered instead of potentially inaccurate values. Add optional strict parameter to these two functions: use strict=False to get the old behavior, accept malformed inputs. getattr(email.utils, ‘supports_strict_parsing’, False) can be use to check if the strict paramater is available. This improves the CVE-2023-27043 fix. gh-123270: Sanitize names in zipfile.Path to avoid infinite loops (gh-122905) without breaking contents using legitimate characters. That’s CVE-2024-8088.

gh-123678 and gh-116741: Upgrade bundled libexpat to 2.6.3 to fix CVE-2024-28757, CVE-2024-45490, CVE-2024-45491 and CVE-2024-45492. gh-118486: os.mkdir() on Windows now accepts mode of 0o700 to restrict the new directory to the current user. This fixes CVE-2024-4030 affecting tempfile.mkdtemp() in scenarios where the base temporary directory is more permissive than the default. gh-123067: Fix quadratic complexity in parsing “-quoted cookie values with backslashes by http.cookies. Fixes CVE-2024-7592. gh-113171: Fixed various false positives and false negatives in IPv4Address.is_private, IPv4Address.is_global, IPv6Address.is_private, IPv6Address.is_global. Fixes CVE-2024-4032. gh-67693: Fix urllib.parse.urlunparse() and urllib.parse.urlunsplit() for URIs with path starting with multiple slashes and no authority. Fixes CVE-2015-2104. gh-121957: Fixed missing audit events around interactive use of Python, now also properly firing for python -i, as well as for python -m asyncio. The event in question is cpython.run_stdin. gh-122133: Authenticate the socket connection for the socket.socketpair() fallback on platforms where AF_UNIX is not available like Windows. gh-121285: Remove backtracking from tarfile header parsing for hdrcharset, PAX, and GNU sparse headers. That’s CVE-2024-6232. gh-114572: ssl.SSLContext.cert_store_stats() and ssl.SSLContext.get_ca_certs() now correctly lock access to the certificate store, when the ssl.SSLContext is shared across multiple threads. gh-102988: email.utils.getaddresses() and email.utils.parseaddr() now return (”, ”) 2-tuples in more situations where invalid email addresses are encountered instead of potentially inaccurate values.
