A tomcat8 security update has been released for Debian GNU/Linux 8 LTS to address the possibility of a man-in-the-middle attack.

Package : tomcat8
Version : 8.0.14-1+deb8u16
CVE ID : CVE-2019-12418

Tomcat8 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.

For Debian 8 "Jessie", this problem has been fixed in version
8.0.14-1+deb8u16.

We recommend that you upgrade your tomcat8 packages.
