   An update that fixes 5 vulnerabilities is now available.

Description:

   This update for tomcat 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.

   CVE-2019-17563 (bsc#1159729) When using FORM authentication there was a
   narrow window where an attacker could perform a session fixation attack.

   CVE-2019-17569 (bsc#1164825) Invalid Transfer-Encoding headers were
   incorrectly processed leading to a possibility of HTTP Request Smuggling
   if Tomcat was located behind a reverse proxy that incorrectly handled the
   invalid Transfer-Encoding header.
