Red Hat: RHSA-2016-0492-01 Moderate: Tomcat6 Security Update

red hat
Calendar Grey March 22, 2016
Dist Redhat Esm H88
An update for Tomcat6 from Red Hat resolves moderate security vulnerabilities and corrects several bugs, with a focus on memory management improvements.
Updated tomcat6 packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 6

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

For details on how to apply this update, refer to:

https://access.redhat.com/articles/11258

Summary

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.
