Upstream update including security & bug fixes as well as feature enhancements.
From the upstream release notes:
When relying on the
--local clone optimization, Git dereferences
symbolic links in the source repository before creating hardlinks
(or copies) of the dereferenced link in the destination repository.
This can lead to surprising behavior where arbitrary files are
present in a repository's
$GIT_DIR when cloning from a malicious
Git will no longer dereference symbolic links via the
clone mechanism, and will instead refuse to clone repositories that
have symbolic links present in the
Additionally, the value of
protocol.file.allow is changed to be
"user" by default.
An overly-long command string given to
git shell can result in
split_cmdline(), leading to arbitrary heap writes and
remote code execution when
git shell is exposed and the directory
git shell is taught to refuse interactive commands that are
longer than 4MiB in size.
split_cmdline() is hardened to reject
inputs larger than 2GiB.
