Affected packages

• crates.io nimiq-transaction: <= 0.2.0 (no fix yet)

Description

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.
