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

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

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in Tomcat 8.

Software Description:
- tomcat8: Servlet and JSP engine

Details:

It was discovered that the Tomcat 8 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 8 did not address HTTP/2 connection window
exhaustion on write while addressing CVE-2019-0199. An attacker could
possibly use this issue to cause a denial of service. (CVE-2019-10072)

Update instructions:

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

Ubuntu 18.04 LTS:
libtomcat8-java 8.5.39-1ubuntu1~18.04.3
tomcat8 8.5.39-1ubuntu1~18.04.3

Ubuntu 16.04 LTS:
libtomcat8-java 8.0.32-1ubuntu1.10
tomcat8 8.0.32-1ubuntu1.10
