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