A security update for Python 3.13 addresses multiple vulnerabilities including denial of service issues in xml.dom.minidom and plistlib modules, excessive read buffering in http.client, and ZIP64 End of Central Directory validation in the zipfile module. The update also fixes performance issues and other bugs. The vulnerabilities have been rated as moderate severity. Patches are available and have been released by vendors including Red Hat.

This update for python313 fixes the following issues: - Update to 3.13.11: - Security - CVE-2025-12084: cpython: Fixed quadratic algorithm in xml.dom.minidom leading to denial of service (bsc#1254997) - CVE-2025-13836: Fixed default Content-Lenght read amount from HTTP response (bsc#1254400) - CVE-2025-13837: Fixed plistlib module denial of service (bsc#1254401) - CVE-2025-8291: Fixed validity of the ZIP64 End of Central Directory (EOCD) not checked by the 'zipfile' module (bsc#1251305) - gh-137836: Add support of the “plaintext” element, RAWTEXT elements “xmp”, “iframe”, “noembed” and “noframes”, and optionally RAWTEXT element “noscript” in html.parser.HTMLParser. - gh-136063: email.message: ensure linear complexity for legacy HTTP parameters parsing. Patch by Bénédikt Tran. - CVE-2025-6075: Fixed performance issues caused by user-controller os.path.expandvars() (bsc#1252974) - Library - gh-140797: Revert changes to the undocumented re.Scanner class. Capturing groups are still allowed for backward compatibility, although using them can lead to incorrect result. They will be forbidden in future Python versions. - gh-142206: The resource tracker in the multiprocessing module now uses the original communication protocol, as in Python 3.14.0 and below, by default. This avoids issues with upgrading Python while it is running. (Note that such ‘in-place’ upgrades are not tested.) The tracker remains compatible with subprocesses that use new protocol (that is, subprocesses using Python 3.13.10, 3.14.1 and 3.15). - Core and Builtins - gh-142218: Fix crash when inserting into a split table dictionary with a non str key that matches an existing key. - Update to 3.13.10: - Tools/Demos - gh-141442: The iOS testbed now correctly handles test arguments that contain spaces. - Tests - gh-140482: Preserve and restore the state of stty echo as part of the test environment. - gh-140082: Update python -m test to set FORCE_COLOR=1 when being run with color enabled so that unittest which is run by it with redirected output will output in color. - gh-136442: Use exitcode 1 instead of 5 if unittest.TestCase.setUpClass() raises an exception - Library - gh-74389: When the stdin being used by a subprocess.Popen instance is closed, this is now ignored in subprocess.Popen.communicate() instead of leaving the class in an inconsistent state. - gh-87512: Fix subprocess.Popen.communicate() timeout handling on Windows when writing large input. Previously, the timeout was ignored during stdin writing, causing the method to block indefinitely if the child process did not consume input quickly. The stdin write is now performed in a background thread, allowing the timeout to be properly enforced. - gh-141473: When subprocess.Popen.communicate() was called with input and a timeout and is called for a second time after a TimeoutExpired exception before the process has died, it should no longer hang. - gh-59000: Fix pdb breakpoint resolution for class methods when the module defining the class is not imported. - gh-141570: Support file-like object raising OSError from fileno() in color detection (_colorize.can_colorize()). This can occur when sys.stdout is redirected. - gh-141659: Fix bad file descriptor errors from _posixsubprocess on AIX. - gh-141497: ipaddress: ensure that the methods IPv4Network.hosts() and IPv6Network.hosts() always return an iterator. - gh-140938: The statistics.stdev() and statistics.pstdev() functions now raise a ValueError when the input contains an infinity or a NaN. - gh-124111: Updated Tcl threading configuration in _tkinter to assume that threads are always available in Tcl 9 and later. - gh-137109: The os.fork and related forking APIs will no longer warn in the common case where Linux or macOS platform APIs return the number of threads in a process and find the answer to be 1 even when a os.register_at_fork() after_in_parent= callback (re)starts a thread. - gh-141314: Fix assertion failure in io.TextIOWrapper.tell() when reading files with standalone carriage return (\r) line endings. - gh-141311: Fix assertion failure in io.BytesIO.readinto() and undefined behavior arising when read position is above capcity in io.BytesIO. - gh-141141: Fix a thread safety issue with base64.b85decode(). Contributed by Benel Tayar. - gh-140911: collections: Ensure that the methods UserString.rindex() and UserString.index() accept collections.UserString instances as the sub argument. - gh-140797: The undocumented re.Scanner class now forbids regular expressions containing capturing

Red Hat Discovery, also known as Discovery, is an inspection and reporting tool that finds, identifies, and reports environment data, or facts, such as the number of physical and virtual systems on a network, their operating systems, and relevant configuration data stored within them. Discovery also identifies and reports more detailed facts for some versions of key Red Hat packages and products that it finds in the network.

A moderate severity security vulnerability (CVE-2025-8291) affects Python 3.12 in Red Hat Enterprise Linux 9.6 Extended Update Support and related products. The issue involves the Python zipfile module where the End of Central Directory (EOCD) Locator record offset is not properly checked. This vulnerability has been addressed by Red Hat in updated python3.12 packages. Users of affected Red Hat Enterprise Linux 9.6 EUS and CodeReady Linux Builder 9.6 should apply the provided security update to remediate the issue.

If the value passed to os.path.expandvars() is user-controlled a performance degradation is possible when expanding environment variables.

The 'zipfile' module would not check the validity of the ZIP64 End of Central Directory (EOCD) Locator record offset value would not be used to locate the ZIP64 EOCD record, instead the ZIP64 EOCD record would be assumed to be the previous record in the ZIP archive. This could be abused to create ZIP archives that are handled differently by the 'zipfile' module compared to other ZIP implementations. Remediation maintains this behavior, but checks that the offset specified in the ZIP64 EOCD Locator record matches the expected value.

CVE-2025-8291 is a medium severity vulnerability in the Python Software Foundation's CPython implementation affecting the 'zipfile' module. The issue arises because the module does not properly validate the offset value in the ZIP64 End of Central Directory (EOCD) Locator record and assumes the ZIP64 EOCD record is the previous record in the archive. This discrepancy can cause the 'zipfile' module to handle certain ZIP archives differently than other ZIP implementations. The remediation maintains the original behavior but adds a check to ensure the offset specified in the ZIP64 EOCD Locator record matches the expected value.
