Summary

nimiq-consensus panics via RequestMacroChain micro-block locator

Details

Impact

An unauthenticated p2p peer can cause the RequestMacroChain message handler task to panic by sending a RequestMacroChain message where the first locator hash that is on the victim’s main chain is a micro block hash (not a macro block hash).

In RequestMacroChain::handle, the handler selects the locator based only on "is on main chain", then calls get_macro_blocks() and panics via .unwrap() when the selected hash is not a macro block (BlockchainError::BlockIsNotMacro).

Patches

The patch for this vulnerability](https://github.com/nimiq/core-rs-albatross/pull/3660) is formally released as part of v1.3.0.

Workarounds
