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.

CVE-2019-12418

	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.

CVE-2019-17563

	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
7.0.56-3+really7.0.99-1.

We recommend that you upgrade your tomcat7 packages.
