-------------------------------------------------------------------------

Package : jetty9 Version : 9.4.16-0+deb10u2 CVE ID : CVE-2022-2047 CVE-2022-2048

Two security vulnerabilities were discovered in Jetty, a Java servlet engine and webserver.

CVE-2022-2047

In Eclipse Jetty 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-2022-2048

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.

For Debian 10 buster, these problems have been fixed in version 9.4.16-0+deb10u2.

We recommend that you upgrade your jetty9 packages.
