✅ 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: There is no complete mitigation while RTCP processing remains exposed. If RTP/RTCP is not needed, disable the affected RTP session handling elements. Otherwise, restrict the negotiated RTCP port to trusted peers with network controls. These measures reduce exposure but do not correct the parser flaw.
