✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: Disable the RDP listener when it is not required, or restrict access to the RDP port to trusted networks or hosts at the network boundary. No application-level mitigation that preserves unrestricted RDP access is known. Workaround: If VNC is not required, disable the gnome-remote-desktop VNC service. If it must remain enabled, restrict the VNC listener to trusted hosts or management networks using host-based firewall rules.
