How to fix?

There is no fixed version for RHEL:7 systemd-python.

NVD Description

Note: Versions mentioned in the description apply only to the upstream systemd-python package and not the systemd-python package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

In systemd before v242-rc4, it was discovered that pam_systemd does not properly sanitize the environment before using the XDG_SEAT variable. It is possible for an attacker, in some particular configurations, to set a XDG_SEAT environment variable which allows for commands to be checked against polkit policies using the "allow_active" element rather than "allow_any".
