RHEL 5 / 6 : JBoss Web Server (RHSA-2014:0835)

medium Nessus Plugin ID 76400

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated tomcat7 packages that fix three security issues 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.

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.

All users of Red Hat JBoss Web Server 2.0.1 are advised to upgrade to these updated tomcat7 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

Update the affected packages.
