There is no fixed version for Centos:8 xorg-x11-server-source.

NVD Description

Note: Versions mentioned in the description apply only to the upstream xorg-x11-server-source package and not the xorg-x11-server-source package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

A flaw was found in the XFIXES extension. The XFixesSetClientDisconnectMode handler does not validate the request length, allowing a client to read unintended memory from previous requests.
