How to fix?

Upgrade sssd to version 2.10.0-beta1 or higher.

Overview

Affected versions of this package are vulnerable to Improper Authorization due to a race condition during the authorization process, which leads to inconsistent application of GPO policies for authenticated users. This inconsistency may result in improper authorization, either granting or denying access to resources inappropriately.

Workaround

This vulnerability can be mitigated by applying a configuration change to the sssd.conf file to make the occurrence of the race condition more difficult: Increase the GPO cache timeout by editing the ad_gpo_cache_timeout directive to a value of 3600, which extends the cache timeout to one hour but may delay GPO updates propagation from the AD server to local machines.
