tomcat8 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in Tomcat.

Software Description:
- tomcat8: Servlet and JSP engine

Details:

It was discovered that Tomcat incorrectly handled the RMI registry when
configured with the JMX Remote Lifecycle Listener. A local attacker could
possibly use this issue to obtain credentials and gain complete control
over the Tomcat instance. (CVE-2019-12418)

It was discovered that Tomcat incorrectly handled FORM authentication. A
remote attacker could possibly use this issue to perform a session fixation
attack. (CVE-2019-17563)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 LTS:
  libtomcat8-java                 8.0.32-1ubuntu1.11
  tomcat8                         8.0.32-1ubuntu1.11
