[ANNOUNCE] Git for Windows 2.45.1 (security bug-fix release)

[Johannes Schindelin]

Dear Git users,

I hereby announce that Git for Windows 2.45.1 is available from:

https://gitforwindows.org/

Changes since Git for Windows v2.45.0 (April 29th 2024):

Git for Windows for Windows v2.45 is the last version to support for
Windows 7 and for Windows 8, see MSYS2's corresponding deprecation
announcement (Git for Windows relies on MSYS2 for components such as
Bash and Perl).

Please also note that the 32-bit variant of Git for Windows is
deprecated; Its last official release is planned for 2025.

Note: the defense-in-depth protection in this update causes a regression
when cloning repositories enabled with Git LFS. The clone will fail with
an error message. The remedy is to call `git lfs pull` in the fresh clone.

New Features

* Comes with Git v2.45.1.

Bug Fixes

* CVE-2024-32002: Recursive clones on case-insensitive filesystems
that support symbolic links are susceptible to case confusion that
can be exploited to execute just-cloned code during the clone
operation.
* CVE-2024-32004: Repositories can be configured to execute arbitrary
code during local clones. To address this, the ownership checks
introduced in v2.30.3 are now extended to cover cloning local
repositories.
* CVE-2024-32020: Local clones may end up hardlinking files into the
target repository's object database when source and target
repository reside on the same disk. If the source repository is
owned by a different user, then those hardlinked files may be
rewritten at any point in time by the untrusted user.
* CVE-2024-32021: When cloning a local source repository that
contains symlinks via the filesystem, Git may create hardlinks to
arbitrary user-readable files on the same filesystem as the target
repository in the objects/ directory.
* CVE-2024-32465: It is supposed to be safe to clone untrusted
repositories, even those unpacked from zip archives or tarballs
originating from untrusted sources, but Git can be tricked to run
arbitrary code as part of the clone.
* Defense-in-depth: submodule: require the submodule path to contain
directories only.
* Defense-in-depth: clone: when symbolic links collide with
directories, keep the latter.
* Defense-in-depth: clone: prevent hooks from running during a clone.
* Defense-in-depth: core.hooksPath: add some protection while
cloning.
* Defense-in-depth: fsck: warn about symlink pointing inside a
gitdir.
* Various fix-ups on HTTP tests.
* HTTP Header redaction code has been adjusted for a newer version of
cURL library that shows its traces differently from earlier
versions.
* Fix was added to work around a regression in libcURL 8.7.0 (which
has already been fixed in their tip of the tree).
* Replace macos-12 used at GitHub CI with macos-13.
* ci(linux-asan/linux-ubsan): let's save some time
* Tests with LSan from time to time seem to emit harmless message
that makes our tests unnecessarily flakey; we work it around by
filtering the uninteresting output.
* Update GitHub Actions jobs to avoid warnings against using
deprecated version of Node.js.
