How to fix?

Upgrade Debian:12 systemd to version 204-5 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream systemd package and not the systemd package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

Integer overflow in the valid_user_field function in journal/journald-native.c in systemd allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large journal data field, which triggers a heap-based buffer overflow.
