CVE-2026-118689 · OvenMediaEngine through 0.21.0 OVT Relay DoS via Oversized payload_length
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
OvenMediaEngine through 0.21.0 contains a denial of service vulnerability in OvtPacket::LoadHeader() that allows unauthenticated attackers to stall connections by sending payload_length values above 32750. Attackers can send crafted OVT packets to the OVT listener to hold connections open indefinitely and accumulate buffered memory, disrupting origin-to-edge stream relay.
