tomcat vulnerabilities
==========================================================================

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

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Tomcat.

Software Description:
- tomcat7: Servlet 3.0 and JSP 2.2 Java API classes

Details:

It was discovered that the Tomcat SSI printenv command echoed user
provided data without escaping it. An attacker could possibly use this
issue to perform an XSS attack. (CVE-2019-0221)

It was discovered that Tomcat incorrectly handled certain uncommon
PersistenceManager with FileStore configurations. A remote attacker could
possibly use this issue to execute arbitrary code.
(CVE-2020-9484, CVE-2021-25329)
