Topic

Updated tomcat6 packages that fix three security issues and one bug are now
available for Red Hat JBoss Web Server 2.0.1 on Red Hat Enterprise Linux 5
and 6.

The Red Hat Security Response Team has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

Description

Red Hat JBoss Web Server is a fully integrated and certified set of
components for hosting Java web applications. It is comprised of the Apache
HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat Connector
(mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and the Tomcat
Native library.

It was discovered that Apache Tomcat did not limit the length of chunk
sizes when using chunked transfer encoding. A remote attacker could use
this flaw to perform a denial of service attack against Tomcat by streaming
an unlimited quantity of data, leading to excessive consumption of server
resources. (CVE-2014-0075)

It was found that Apache Tomcat did not check for overflowing values when
parsing request content length headers. A remote attacker could use this
flaw to perform an HTTP request smuggling attack on a Tomcat server located
behind a reverse proxy that processed the content length header correctly.
(CVE-2014-0099)

It was found that the org.apache.catalina.servlets.DefaultServlet
implementation in Apache Tomcat allowed the definition of XML External
Entities (XXEs) in provided XSLTs. A malicious application could use this
to circumvent intended security restrictions to disclose sensitive
information. (CVE-2014-0096)

The CVE-2014-0075 issue was discovered by David Jorm of Red Hat Product
Security.

This update also fixes the following bug:

The tomcat6-lib-6.0.37-19_patch_04.ep6.el5 package, provided as a
dependency of Red Hat JBoss Web Server 2.0.1, included a build of
commons-dbcp.jar that used an incorrect java package name, causing
applications using this dependency to not function properly. With this
update, the java package name has been corrected. (BZ#1101287)

All users of Red Hat JBoss Web Server 2.0.1 are advised to upgrade to these
updated tomcat6 packages, which contain backported patches to correct these
issues. The Red Hat JBoss Web Server process must be restarted for the
update to take effect.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied, and back up your existing Red
Hat JBoss Web Server installation (including all applications and
configuration files).

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258
