The following public repositories all have a copy of the 'v2.40.1'

The addressed issues are:
* CVE-2023-25652:
By feeding specially crafted input to `git apply --reject`, a
path outside the working tree can be overwritten with partially
controlled contents (corresponding to the rejected hunk(s) from
the given patch).
* CVE-2023-25815:
When Git is compiled with runtime prefix support and runs without
translated messages, it still used the gettext machinery to
display messages, which subsequently potentially looked for
translated messages in unexpected places. This allowed for
malicious placement of crafted messages.
* CVE-2023-29007:
When renaming or deleting a section from a configuration file,
certain malicious configuration values may be misinterpreted as
the beginning of a new configuration section, leading to arbitrary
configuration injection.
