A vulnerability was found in Undertow, where the chunked response hangs
after the body was flushed. The response headers and body were sent but the
client would continue waiting as Undertow does not send the expected 0\r\n
termination of the chunked response. This results in uncontrolled resource
consumption, leaving the server side to a denial of service attack. This
happens only with Java 17 TLSv1.3 scenarios.
