If Apache Tomcat 8.5.0 to 8.5.82, 9.0.0-M1 to 9.0.67, 10.0.0-M1 to 10.0.26
or 10.1.0-M1 to 10.1.0 was configured to ignore invalid HTTP headers via
setting rejectIllegalHeader to false (the default for 8.5.x only), Tomcat
did not reject a request containing an invalid Content-Length header making
a request smuggling attack possible if Tomcat was located behind a reverse
proxy that also failed to reject the request with the invalid header.
