NVD Description

Note: Versions mentioned in the description apply only to the upstream tigervnc-server-module package and not the tigervnc-server-module package as distributed by RHEL.

A vulnerability was found in X.Org. This security flaw occurs because the handler for the ScreenSaverSetAttributes request may write to memory after it has been freed. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions.
