How to fix?

Overview

org.apache.tomcat:tomcat-coyote is a Tomcat Connectors and HTTP parser.

Affected versions of this package are vulnerable to Insufficient Session Expiration due to an infinite timeout being assigned to an open connection improperly, in http2/Stream.java. An attacker can force this situation by sending an HTTP/2 stream with excessive headers, causing an out-of-memory error or exhausting maxConnections.
