    Two security vulnerabilities have been fixed in the Tomcat servlet and JSP engine. CVE-2019-12418
    Package        : tomcat7
    Version        : 7.0.56-3+really7.0.99-1
    CVE ID         : CVE-2019-12418 CVE-2019-17563
    Two security vulnerabilities have been fixed in the Tomcat
    servlet and JSP engine.
    	When Apache Tomcat is configured with the JMX Remote Lifecycle
            Listener, a local attacker without access to the Tomcat process
            or configuration files is able to manipulate the RMI registry to
            perform a man-in-the-middle attack to capture user names and
            passwords used to access the JMX interface. The attacker can
            then use these credentials to access the JMX interface and gain
            complete control over the Tomcat instance.
    	When using FORM authentication with Apache Tomcat there was a
            narrow window where an attacker could perform a session fixation
            attack. The window was considered too narrow for an exploit to
            be practical but, erring on the side of caution, this issue has
            been treated as a security vulnerability.
    For Debian 8 "Jessie", these problems have been fixed in version
    We recommend that you upgrade your tomcat7 packages.
