Synopsis

The remote Red Hat host is missing a security update for tomcat6.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2016:0492 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL tomcat6 package based on the guidance in RHSA-2016:0492.
