Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The nostr-relay-pool crate for Rust is affected in versions before 0.44.3. A malicious relay can flood the client with NIP-42 authentication challenges faster than they can be answered, and the client queues every one without limit, so memory use and pending signer operations grow until the client becomes unavailable. Upgrade to version 0.44.3, which keeps only the latest pending challenge. The source gives no workaround.
