libp2p-rendezvous through 0.17.1 Denial of Service via Unbounded Registration TTL in Discovery Responses
libp2p-rendezvous through 0.17.1 fails to validate registration TTL values in discovery responses, allowing attackers to trigger timer arithmetic overflow. A malicious rendezvous server can send a discovery response with an unbounded TTL value that causes the client node process to panic when computing the expiry timer.
