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, restrict network access to applications utilizing FFmpeg for RTP/ASF stream demuxing, ensuring only trusted sources can provide such streams. Implement firewall rules to limit inbound connections to the affected services. This may impact legitimate functionality if trusted sources are inadvertently blocked.
