Hello,
I am upgrading my debian 11 to debian 12 and all my systems are affected by this bug. The systems are fully upgraded and the bug is persistent. $ apt info login [...] Version: 1:4.13+dfsg-1+b1 [...] $ apt info passwd [...] Version: 1:4.13+dfsg1-1+b1 [...] No only the upgrade process is affected, but most commands that read /etc/login.defs : useradd, userdell, groupmems, ... etc. As I am an user of QubesOS, I reported the bug first on : https://github.com/QubesOS/qubes-issues/issues/8559 It should not matter as the relevant programs come from debian bookworm stable.
