Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

An unauthenticated remote attacker who can send a single UDP packet to a Spring Integration UDP inbound adapter can cause the server to emit an outbound UDP datagram to an arbitrary internal or external host and port of the attacker's choosing.
