Name of the Vulnerable Software and Affected Versions nimiq/core-rs-albatross versions prior to 1.3.0

Description An unauthenticated p2p peer can cause the RequestMacroChain message handler task to panic. This occurs when a RequestMacroChain message is sent where the first locator hash on the victim's main chain is a micro block hash instead of a macro block hash. The RequestMacroChain::handle handler selects the locator based only on whether it is on the main chain, then calls get macro blocks() and panics via .unwrap() when the selected hash is not a macro block (BlockchainError::BlockIsNotMacro).

Recommendations Update to version 1.3.0.
