SUSE-RU-2026:1228-1

This update for shadow fixes the following issues:

shadow is updated to 4.17.2 to bring lots of features and bug fixes.

• util-linux-2.41 introduced new variable: LOGIN_ENV_SAFELIST. Recognize it and update dependencies.

• Set SYS_{UID,GID}_MIN to 201: After repeated similar requests to change the ID ranges we set the above mentioned value to 201. The max value will stay at 499. This range should be sufficient and will give us leeway for the future. It's not straightforward to find out which static UIDs/GIDs are used in all packages.

Update to 4.17.2:

• src/login_nopam.c: Fix compiler warnings #1170
• lib/chkname.c: Put limits for LOGIN_NAME_MAX and sysconf(_SC_LOGIN_NAME_MAX) #1169
