DescriptionNVD

Impact

HistoryTreeProof::verify panics on a malformed proof where history.len() != positions.len() due to assert_eq!(history.len(), positions.len()).

The proof object is derived from untrusted p2p responses (ResponseTransactionsProof.proof) and is therefore attacker-controlled at the network boundary until validated. A malicious peer could trigger a crash by returning a crafted inclusion proof with a length mismatch.

Patches

The patch for this vulnerability is included as part of v1.3.0.

Workarounds

No known workarounds know.

AnalysisAI

Nimiq Core-rs-Albatross prior to v1.3.0 crashes when processing malformed transaction inclusion proofs with mismatched history and positions arrays. A remote attacker can trigger a denial of service by sending a crafted ResponseTransactionsProof with unequal array lengths, causing the HistoryTreeProof::verify function to panic. …
