How to fix?

Upgrade Debian:unstable python-git to version 3.1.61-1 or higher.

NVD Description

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

GitPython before 3.1.56 contains an argument injection vulnerability in the Commit.count() method, which forwards keyword arguments to 'git rev-list' without the check_unsafe_options guard present in the sibling iter_items method. An attacker who can control options passed to Commit.count (e.g., via an application that forwards a user-supplied options dict) can supply output=<path>, causing 'git rev-list --output=<path>' to open and truncate the target file to zero bytes before revision parsing. This allows destruction/blanking of an arbitrary file at the process's privilege level (no content control, 0-byte truncation).
