(bsc#1254401, gh#python/cpython#119342) CVE-2025-13837-plistlib-mailicious-length.patch ------------------------------------------------------------------- Wed Nov 19 19:21:41 UTC 2025 - Matej Cepl - Add pass-test_write_read_limited_history.patch: Fix readline history truncation when length is reduced The `readline.set_history_length()` function did not previously truncate the in-memory history when the new length was set to a value smaller than the current number of history items. This could lead to unexpected behavior where `get_history_length()` would still report the old length and writing the history to a file would write more entries than the new limit. This patch modifies `set_history_length()` to explicitly remove the oldest history entries using `remove_history()` when the length is decreased, ensuring the in-memory history is correctly truncated to the new limit. This brings the function's behavior in line with expectations and fixes failures in `test_write_read_limited_history`. ------------------------------------------------------------------- Thu Nov 13 17:13:03 UTC 2025 - Matej Cepl - Add CVE-2025-6075-expandvars-perf-degrad.patch avoid simple quadratic complexity vulnerabilities of os.path.expandvars() (CVE-2025-6075, bsc#1252974). - Reapply patches: - bsc1243155-sphinx-non-determinism.patch - doc-py38-to-py36.patch - fix_configure_rst.patch ------------------------------------------------------------------- Wed Oct 15 09:10:21 UTC 2025 - Daniel Garcia - Update to 3.12.12: - Tools/Demos - gh-139330: SBOM generation tool didn’t cross-check the version and checksum values against the Modules/expat/refresh.sh script, leading to the values becoming out-of-date during routine updates. - Security - gh-139700: Check consistency of the zip64 end of central directory record. Support records with “zip64 extensible data” if there are no bytes prepended to the ZIP file (CVE-2025-8291, bsc#1251305). - gh-139400: xml.parsers.expat: Make sure that parent Expat parsers are only garbage-collected once they are no longer referenced by subparsers created by ExternalEntityParserCreate(). Patch by Sebastian Pipping. - gh-135661: Fix parsing start and end tags in html.parser.HTMLParser according to the HTML5 standard. * Whitespaces no longer accepted between does not end the script section. * Vertical tabulation (\v) and non-ASCII whitespaces no longer recognized as whitespaces. The only whitespaces are \t\n\r\f and space. * Null character (U+0000) no longer ends the tag name. * Attributes and slashes after the tag name in end tags are now ignored, instead of terminating after the first > in quoted attribute value. E.g. . * Multiple slashes and whitespaces between the last attribute and closing > are now ignored in both start and end tags. E.g. . * Multiple = between attribute name and value are no longer collapsed. E.g. produces attribute “foo” with value “=bar”. - gh-135661: Fix CDATA section parsing in html.parser.HTMLParser according to the HTML5 standard: ] ]> and ]] > no longer end the CDATA section. Add private method _set_support_cdata() which can be used to specify how to parse <[CDATA[ — as a CDATA section in foreign content (SVG or MathML) or as a bogus comment in the HTML namespace. - gh-102555: Fix comment parsing in html.parser.HTMLParser according to the HTML5 standard. --!> now ends the comment. -- > no longer ends the comment.
