CVE-2023-26604  (opens in a new tab)

How to fix?

Upgrade Centos:8 systemd-pam to version 0:239-74.el8_8.2 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 before 247 does not adequately block local privilege escalation for some Sudo configurations, e.g., plausible sudoers files in which the "systemctl status" command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This presents a substantial security risk when running systemctl from Sudo, because less executes as root when the terminal size is too small to show the complete systemctl output.
