Package: systemd Version: 245-2 Severity: serious Forwarded: https://github.com/systemd/systemd/issues/15141
Usernames that contain a number (or digit) as first character are rejected by v245: https://github.com/systemd/systemd/blob/v245/src/basic/user-util.c#L710 This will lead to login failures. By default, adduser will not allow such usernames to be created, but can be forced to do so via --force-badname. While a leading dot is really questionable, the validation should be relaxed for a leading number. -- Package-specific info: -- System Information: Debian Release: bullseye/sid APT prefers unstable APT policy: (500, 'unstable'), (200, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.4.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages systemd depends on: ii adduser 3.118 ii libacl1 2.2.53-6 ii libapparmor1 2.13.3-7 ii libaudit1 1:2.8.5-2+b1 ii libblkid1 2.34-0.1 ii libc6 2.30-2 ii libcap2 1:2.32-1 ii libcrypt1 1:4.4.15-1 ii libcryptsetup12 2:2.3.0-1 ii libgcrypt20 1.8.5-5 ii libgnutls30 3.6.12-2 ii libgpg-error0 1.37-1 ii libidn2-0 2.3.0-1 ii libip4tc2 1.8.4-3 ii libkmod2 27-2 ii liblz4-1 1.9.2-2 ii liblzma5 5.2.4-1+b1 ii libmount1 2.34-0.1 ii libpam0g 1.3.1-5 ii libpcre2-8-0 10.34-7 ii libseccomp2 2.4.3-1 ii libselinux1 3.0-1+b1 ii libsystemd0 245-2 ii mount 2.34-0.1 ii util-linux 2.34-0.1 Versions of packages systemd recommends: ii dbus 1.12.16-2 Versions of packages systemd suggests: ii policykit-1 0.105-26 ii systemd-container 245-2 Versions of packages systemd is related to: ii dracut 048+80-2 pn initramfs-tools <none> ii libnss-systemd 245-2 ii libpam-systemd 245-2 ii udev 245-2 -- no debconf information
