Core and Builtins
- gh-120384: Fix an array out of bounds crash in
list_ass_subscript, which could be invoked via some
specificly tailored input: including concurrent
modification of a list object, where one thread assigns
a slice and another clears it.
- gh-120298: Fix use-after free in list_richcompare_impl
which can be invoked via some specificly tailored evil

- 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.
- 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-121227: Raise an SSL.SSLError if an empty protocols argument
is passed to ssl.SSLContext.set_npn_protocols() to fix
CVE-2024-5642.
- gh-135661: Fix parsing start and end tags in
html.parser.HTMLParser according to the HTML5 standard.
* Whitespaces no longer accepted between </ and the tag name.
E.g. </ script> 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. </script/foo=">"/>.
* Multiple slashes and whitespaces between the last attribute
and closing > are now ignored in both start and end tags. E.g.
<a foo=bar/ //>.
* Multiple = between attribute name and value are no longer
collapsed. E.g. <a foo==bar> produces attribute “foo” with
value “=bar”.
