Apache Tomcat 5.5.0 and 4.1.0 through 4.1.31 allows remote attackers to bypass an IP address restriction and obtain sensitive information via a request that is processed concurrently with another request but in a different thread, leading to an instance-variable overwrite associated with a synchronization problem and lack of thread safety, and related to RemoteFilterValve, RemoteAddrValve, and RemoteHostValve.
