Fixes CVE-2022-39260
Git v2.38.1 Release Notes
=========================
This release merges the security fix that appears in v2.30.6; see
the release notes for that version for details.
Excerpt from 2.30.6 release notes:
* CVE-2022-39260:
An overly-long command string given to `git shell` can result in
overflow in `split_cmdline()`, leading to arbitrary heap writes and
remote code execution when `git shell` is exposed and the directory
`$HOME/git-shell-commands` exists.
`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.
