tomcat7, tomcat8 vulnerabilities
==========================================================================

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

- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Tomcat.

Software Description:
- tomcat8: Servlet and JSP engine
- tomcat7: Servlet and JSP engine

Details:

It was discovered that Tomcat incorrectly handled decoding certain
UTF-8 strings. A remote attacker could possibly use this issue to cause
Tomcat to crash, resulting in a denial of service. (CVE-2018-1336)

It was discovered that the Tomcat WebSocket client incorrectly performed
hostname verification. A remote attacker could possibly use this issue to
intercept sensitive information. (CVE-2018-8034)

Update instructions:

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

Ubuntu 16.04 LTS:
libtomcat8-java 8.0.32-1ubuntu1.7
tomcat8 8.0.32-1ubuntu1.7

Ubuntu 14.04 LTS:
libtomcat7-java 7.0.52-1ubuntu0.15
tomcat7 7.0.52-1ubuntu0.15

In general, a standard system update will make all the necessary changes.
