    Tomcat is the servlet container that is used in the official Reference
    Implementation for the Java Servlet and JavaServer Pages technologies.
    The Java Servlet and JavaServer Pages specifications are developed by
    Sun under the Java Community Process.
    Tomcat is developed in an open and participatory environment and
    released under the Apache Software License version 2.0. Tomcat is intended
    to be a collaboration of the best-of-breed developers from around the world.
    CVE-2016-0762
    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.
    CVE-2016-5018
    In Apache Tomcat 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 a malicious web
    application was able to bypass a configured SecurityManager via a
    Tomcat utility method that was accessible to web applications.
    CVE-2016-6794
    When a SecurityManager is configured, a web application's ability to
    read system properties should be controlled by the SecurityManager. In
    Apache Tomcat 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, 6.0.0 to 6.0.45 the system property
    replacement feature for configuration files could be used by a
    malicious web application to bypass the SecurityManager and read
    system properties that should not be visible.
    CVE-2016-6796
    A malicious web application running on Apache Tomcat 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 was able to bypass a configured SecurityManager via
    manipulation of the configuration parameters for the JSP Servlet.
    CVE-2016-6797
    The ResourceLinkFactory implementation in Apache Tomcat 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 limit web application access to global JNDI
    resources to those resources explicitly linked to the web application.
    Therefore, it was possible for a web application to access any global
    JNDI resource whether an explicit ResourceLink had been configured or
    not.
