nimiq-consensus panics via RequestMacroChain micro-block locator

nimiq/core-rs-albatross is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. In versions 1.2.2 and below, an unauthenticated p2p peer can cause the RequestMacroChain message handler task to panic. Sending a RequestMacroChain message where the first locator hash on the victim’s main chain is a micro block hash (not a macro block hash) causes said panic. The RequestMacroChain::handle 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). This issue has been fixed in version 1.3.0.

core-rs-albatross 安全漏洞

core-rs-albatross是Nimiq开源的一个Albatross协议的Rust实现。 core-rs-albatross 1.2.2及之前版本存在安全漏洞，该漏洞源于未经身份验证的p2p对等方可导致RequestMacroChain消息处理程序任务崩溃，可能导致拒绝服务。
