nimiq-transaction provides the transaction primitive to be used in Nimiq's Rust implementation. Prior to version 1.3.0, 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. The patch for this vulnerability is included as part of v1.3.0. No known workarounds are available.
