    - gh-115398: Allow controlling Expat >=2.6.0 reparse deferral
      (CVE-2023-52425) by adding five new methods:
        xml.etree.ElementTree.XMLParser.flush()
        xml.etree.ElementTree.XMLPullParser.flush()
        xml.parsers.expat.xmlparser.GetReparseDeferralEnabled()
        xml.parsers.expat.xmlparser.SetReparseDeferralEnabled()
        xml.sax.expatreader.ExpatParser.flush()
    - gh-115399: Update bundled libexpat to 2.6.0
    - gh-113659: Skip .pth files with names starting with a dot
      or hidden file attribute.
  - Core and Builtins
    - gh-102388: Fix a bug where iso2022_jp_3 and iso2022_jp_2004
      codecs read out of bounds
  - Library
    - gh-115197: urllib.request no longer resolves the hostname
      before checking it against the system’s proxy bypass list
      on macOS and Windows.
    - gh-115133: Fix tests for XMLPullParser with Expat 2.6.0.
    - gh-81194: Fix a crash in socket.if_indextoname() with
      specific value (UINT_MAX). Fix an integer overflow in
      socket.if_indextoname() on 64-bit non-Windows platforms.
    - gh-109858: Protect zipfile from “quoted-overlap”
      zipbomb. It now raises BadZipFile when try to read an entry
      that overlaps with other entry or central directory.
    - gh-107077: Seems that in some conditions, OpenSSL will
      return SSL_ERROR_SYSCALL instead of SSL_ERROR_SSL
      when a certification verification has failed, but
      the error parameters will still contain ERR_LIB_SSL

From f2eebf3c38eae77765247791576b437ec25ccfe2 Mon Sep 17 00:00:00 2001
From: Serhiy Storchaka <storchaka@gmail.com>
Date: Sun, 11 Feb 2024 12:08:39 +0200
Subject: [PATCH] gh-115133: Fix tests for XMLPullParser with Expat 2.6.0
(GH-115164)
Feeding the parser by too small chunks defers parsing to prevent
CVE-2023-52425. Future versions of Expat may be more reactive.
(cherry picked from commit 4a08e7b3431cd32a0daf22a33421cd3035343dc4)
Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>

xml.etree.ElementTree.XMLParser.flush()
xml.etree.ElementTree.XMLPullParser.flush()
xml.parsers.expat.xmlparser.GetReparseDeferralEnabled()
xml.parsers.expat.xmlparser.SetReparseDeferralEnabled()
xml.sax.expatreader.ExpatParser.flush()
- gh-115399: Update bundled libexpat to 2.6.0
- gh-113659: Skip .pth files with names starting with a dot
or hidden file attribute.
- Core and Builtins
- gh-102388: Fix a bug where iso2022_jp_3 and iso2022_jp_2004

- Library
- gh-115197: urllib.request no longer resolves the hostname
before checking it against the system’s proxy bypass list
on macOS and Windows.
- gh-115133: Fix tests for XMLPullParser with Expat 2.6.0.
- gh-81194: Fix a crash in socket.if_indextoname() with

- gh-109858: Protect zipfile from “quoted-overlap”
zipbomb. It now raises BadZipFile when try to read an entry
that overlaps with other entry or central directory.
- gh-107077: Seems that in some conditions, OpenSSL will
return SSL_ERROR_SYSCALL instead of SSL_ERROR_SSL
when a certification verification has failed, but
the error parameters will still contain ERR_LIB_SSL
and SSL_R_CERTIFICATE_VERIFY_FAILED. We are now
detecting this situation and raising the appropiate
ssl.SSLCertVerificationError. Patch by Pablo Galindo
- gh-91133: Fix a bug in tempfile.TemporaryDirectory cleanup,
which now no longer dereferences symlinks when working
around file system permission errors.
- Documentation
- gh-115399: Document CVE-2023-52425 of Expat <2.6.0 under
“XML vulnerabilities”.
- Tools/Demos
- gh-109991: Update GitHub CI workflows to use OpenSSL 3.0.11
and multissltests to use 1.1.1w and 3.0.11.
- Remove upstreamed patches:
- CVE-2023-6597-TempDir-cleaning-symlink.patch
- libexpat260.patch
