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.
