Aws Smithy Http Server
Monthly
Denial of service in Amazon's aws-smithy-http-server Rust crate (versions prior to 0.66.5) lets remote unauthenticated attackers exhaust server sockets and async tasks by opening many connections and trickling partial requests that never complete. The default serve() path ships without connection read/header timeouts or a concurrent-connection cap, so a classic slowloris-style flood can hang the service indefinitely. No public exploit has been identified at time of analysis, though the technique is well-understood and the CVSS 4.0 base score is 8.7 (High).
