Overview
org.apache.tomcat:tomcat-coyote is a Tomcat Connectors and HTTP parser.
Affected versions of this package are vulnerable to Information Exposure.

While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests.
