+
+ <p>Tomcat did not limit HTTP/0.9 requests to the GET method. If a security

+
+ <p>Tomcat did not validate that the host name provided via the SNI
extension
+ was the same as the host name provided in the HTTP host header field. If
+ Tomcat was configured with more than one virtual host and the TLS
+ configuration for one of those hosts did not require client certificate
