org.eclipse.jetty/jetty-server: Eclipse Jetty: Denial of Service due to unreleased JDK Inflater from compressed HTTP requests

A flaw was found in org.eclipse.jetty. A remote attacker can exploit this vulnerability by sending a compressed HTTP request with Content-Encoding: gzip when the server's response is not compressed. This prevents the release of the JDK Inflater, leading to a resource leak. This resource exhaustio...
