(RHSA-2016:22545) Moderate: tomcat6 security and bug fix update

Apache Tomcat is a servlet container for the Java Servlet and JavaServer
Pages (JSP) technologies.

It was found that the expression language resolver evaluated expressions
within a privileged code section. A malicious web application could use
this flaw to bypass security manager protections. (CVE-2014-7810)

This update also fixes the following bug:

• Previously, using a New I/O (NIO) connector in the Apache Tomcat 6
  servlet resulted in a large memory leak. An upstream patch has been applied
  to fix this bug, and the memory leak no longer occurs. (BZ#1301646)

All Tomcat 6 users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. Tomcat must be
restarted for this update to take effect.
