✅ 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: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability. Workaround: To mitigate this issue, avoid connecting to untrusted or unverified RDP servers. Users should only establish RDP connections with known and trusted servers. If connecting to untrusted servers is unavoidable, consider using a sandbox environment or a dedicated, isolated system for such connections to limit potential impact.
