✅ 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 Remote Desktop Protocol (RDP) servers or opening untrusted RDP files. Users can also disable persistent caching in FreeRDP by using the `--disable-persistent-caching` command-line option when launching `xfreerdp` or similar FreeRDP clients. This may impact performance for frequently accessed RDP sessions.
