debian_rustsec## Summary `hazardous::mac::blake2b::Blake2b::reset()` does not correctly reset the state when a key is supplied that has a different length than the one used upon initialization with `hazardous::mac::blake2b::Blake2b::new()`, because it errorneously uses a cached length. ## Impact Initialization `hazardous::mac::blake2b::Blake2b` with a key of some length `N`, followed by a reset with a key of length `!= N` will produce an incorrect BLAKE2b tag, causing `hazardous::mac::blake2b::Blake2b::verify()` to fail. This means under honest protocol conditions, parties could experience failing tag verifications. ## Resolution Upgrade to `v0.17.16` or `v0.18.1`.
