nimiq-blockchain provides persistent block storage for Nimiq's Rust implementation. In versions 1.3.0 and prior, network-libp2p discovery accepts signed PeerContact updates from untrusted peers and stores them in a peer contact book, eventually leading to address book crash. A PeerContact can legally contain an empty addresses list (no intrinsic validation enforces non-empty). Later, PeerContactBook::known_peers builds an address book by taking addresses.first().expect("every peer should have at least one address"). If the attacker has inserted a signed peer contact with addresses=[], any call to get_address_book (RPC/web client) can panic and crash the node/RPC task depending on panic settings. This issue has been fixed in version 1.4.0.
AnalysisAI
Panic-triggered denial of service in Nimiq's core-rs-albatross (versions prior to 1.4.0) allows a network-level attacker to crash the node's RPC task by injecting a signed PeerContact with an empty addresses list into the libp2p peer discovery layer. The crash is deferred: the malicious contact is accepted and stored silently, but any subsequent call to get_address_book - from an RPC client or web client - triggers an unconditional Rust panic via .expect() on an empty iterator. …
