Description
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 exhaustion can result in a Denial of Service (DoS), making the server unavailable to legitimate users.
Statement
This Important flaw in Eclipse Jetty's GzipHandler can lead to a denial of service in affected Red Hat products. The vulnerability arises when compressed HTTP requests are processed without a corresponding compressed response, causing a resource leak that can exhaust system resources and render the service unavailable.
