  "title": "Malformed consensus message denial of service in Tari Ootle",
  "summary": "Tari Ootle v0.41.2 validator nodes can mishandle semantically incomplete consensus messages received over libp2p. An unauthenticated peer able to reach a validator's public P2P interface can interrupt its consensus worker; gossip delivery can affect multiple reachable validators, and recovery near an epoch transition may leave a node out of sync.",
  "mitigation": "Restrict validator P2P access and consensus-gossip participation to trusted peers or networks where deployment controls permit it. Monitor affected validators for recovery loops or consensus divergence, and apply a vendor-provided corrected release when one is published.",
