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 X Record extension. The RecordSanityCheckRegisterClients function does not check for an integer overflow when computing request length, which allows a client to bypass length checks.
