How to fix?

Upgrade Centos:8 systemd-pam to version 0:239-45.el8 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream systemd-pam package and not the systemd-pam package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

systemd through v245 mishandles numerical usernames such as ones composed of decimal digits or 0x followed by hex digits, as demonstrated by use of root privileges when privileges of the 0x0 user account were intended. NOTE: this issue exists because of an incomplete fix for CVE-2017-1000082.
