✅ Remediation

Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, 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: 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 processing VobSub subtitle files from untrusted or unknown sources. For applications that utilize FFmpeg's VobSub demuxer, consider running them within a sandboxed environment to restrict the potential impact of a successful exploit. 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.
