The Realm implementations in Apache Tomcat versions 9.0.0.M1 to 9.0.0.M9,
8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45
did not process the supplied password if the supplied user name did not
exist. This made a timing attack possible to determine valid user names.
Note that the default configuration includes the LockOutRealm which makes
exploitation of this vulnerability harder.
