Title
nimiq-primitives: Node crash due to missing interlink validation in election macro block proposals
Summary
nimiq-primitives contains primitives (e.g., block, account, transaction) to be used in Nimiq's Rust implementation. Prior to version 1.3.0, an untrusted p2p peer can cause a node to panic by announcing an election macro block whose `validators` set contains an invalid compressed BLS voting key. Hashing an election macro header hashes `validators` and reaches `Validators::voting_keys()`, which calls `validator.voting_key.uncompress().unwrap()` and panics on invalid bytes. The patch for this vulnerability is included as part of v1.3.0. No known workarounds are available.

Prior to version 1.3.0, an untrusted p2p peer can cause a node to panic by announcing an election macro block whose `validators` set contains an invalid compressed BLS voting key. Hashing an election macro header hashes `validators` and reaches `Validators::voting_keys()`, which calls `validator.voting_key.uncompress().unwrap()` and panics on invalid bytes. The patch for this vulnerability is included as part of v1.3.0. No known workarounds are available."
