✅ 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: Avoid opening HLS, DASH, or MSS manifests from untrusted network sources. Run GStreamer-based applications with minimal filesystem access using Linux namespaces or containers, restricting the process to only the directories it legitimately requires. Where feasible, use network controls to limit which manifest hosts the application may contact. These measures reduce risk but do not remove the vulnerability.
