"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.
