Package : jetty9
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 the stable distribution (bullseye), these problems have been fixed in
version 9.4.39-3+deb11u1.

We recommend that you upgrade your jetty9 packages.
