Description
nimiq/core-rs-albatross is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. The `nimiq-network-libp2p` subcrate of nimiq/core-rs-albatross is vulnerable to a Denial of Service (DoS) attack due to uncontrolled memory allocation. Specifically, the implementation of the `Discovery` network message handling allocates a buffer based on a length value provided by the peer, without enforcing an upper bound. Since this length is a `u32`, a peer can t
