Summary

Apache Tomcat 5.5.0 through 5.5.29 and 6.0.0 through 6.0.26 might allow remote attackers to discover the server's hostname or IP address by sending a request for a resource that requires (1) BASIC or (2) DIGEST authentication, and then reading the realm field in the WWW-Authenticate header in the reply.
