In Eclipse Jetty HTTP/2 server implementation, when encountering an invalid HTTP/2 request, the error handling has a bug that can wind up not properly cleaning up the active connections and associated resources. This can lead to a Denial of Service scenario where there are no enough resources left to process good requests.

Affected: Maven: org.eclipse.jetty.http2:http2-server

### Description Invalid HTTP/2 requests (for example, invalid URIs) are incorrectly handled by writing a blocking error response directly from the selector thread. If the client manages to exhaust the HTTP/2 flow control window, or TCP congest the connection, the selector thread will be blocked trying to write the error response. If this is repeated for all the selector threads, the server becomes unresponsive, causing the denial of service.

### Impact A malicious client may render the server unresponsive.

### Patches The fix is available in Jetty versions 9.4.47. 10.0.10, 11.0.10.

### Workarounds No workaround available within Jetty itself. One possible workaround is to filter the requests before sending them to Jetty (for example in a proxy)

Jetty is a 100% Java HTTP Server and Servlet Container. This means that you do not need to configure and run a separate web server (like Apache) in order to use Java, servlets and JSPs to generate dynamic content. Jetty is a fully featured web server for static and dynamic content. Unlike separate server/container solutions, this means that your web server and web application run in the same process, without interconnection overheads and complications. Furthermore, as a pure java component, Jetty can be simply included in your application for demonstration, distribution or deployment. Jetty is available on all Java supported platforms. Security Fix(es): In Eclipse Jetty HTTP/2 server implementation, when encountering an invalid HTTP/2 request, the error handling has a bug that can wind up not properly cleaning up the active connections and associated resources. This can lead to a Denial of Service scenario where there are no enough resources left to process good requests.(CVE-2022-2048) In Eclipse Jetty versions 9.4.0 thru 9.4.46, and 10.0.0 thru 10.0.9, and 11.0.0 thru 11.0.9 versions, the parsing of the authority segment of an http scheme URI, the Jetty HttpURI class improperly detects an invalid input as a hostname. This can lead to failures in a Proxy scenario.(CVE-2022-2047)
