   An update that fixes three vulnerabilities is now available.

Description:

   This update for tomcat6 fixes the following issues:

   CVE-2020-9484 (bsc#1171928) Apache Tomcat Remote Code Execution via
   session persistence

   If an attacker was able to control the contents and name of a file on a
   server configured to use the PersistenceManager, then the attacker could
   have triggered a remote code execution via deserialization of the file
   under their control.

   CVE-2019-12418 (bsc#1159723) Local privilege escalation by manipulating
   the RMI registry and performing a man-in-the-middle attack

   When Tomcat is configured with the JMX Remote Lifecycle Listener, a local
   attacker without access to the Tomcat process or configuration files was
   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 could then use these credentials to access the JMX interface and
   gain complete control over the Tomcat instance.

   CVE-2019-0221 (bsc#1136085) The SSI printenv command echoed user provided
   data without escaping, which made it vulnerable to XSS.
