How to fix?

Upgrade Debian:11 git to version 1:2.17.1-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream git package and not the git package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

In Git before 2.13.7, 2.14.x before 2.14.4, 2.15.x before 2.15.2, 2.16.x before 2.16.4, and 2.17.x before 2.17.1, remote code execution can occur. With a crafted .gitmodules file, a malicious project can execute an arbitrary script on a machine that runs "git clone --recurse-submodules" because submodule "names" are obtained from this file, and then appended to $GIT_DIR/modules, leading to directory traversal with "../" in a name. Finally, post-checkout hooks from a submodule are executed, bypassing the intended design in which hooks are not obtained from a remote server.
