Debian 11: DSA-5332-1 Critical: Git Remote Code Execution Threats

This update includes two changes of behavior that may affect certain setup:
- It stops when directory traversal changes ownership from the current
user while looking for a top-level git directory, a user could make an
exception by using the new safe.directory configuration.
- The default of protocol.file.allow has been changed from "always" to
"user".

For the stable distribution (bullseye), these problems have been fixed in
version 1:2.30.2-1+deb11u1.

We recommend that you upgrade your git packages.
