"Red Hat JBoss Web Server 3.0.3 is now available for Red Hat Enterprise
Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) 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.

This release of Red Hat JBoss Web Server 3.0.3 serves as a replacement
for Red Hat JBoss Web Server 3.0.2, and includes bug fixes and
enhancements, which are documented in the Release Notes documented
linked to in the References.

Security Fix(es) :

* A session fixation flaw was found in the way Tomcat recycled the
requestedSessionSSL field. If at least one web application was
configured to use the SSL session ID as the HTTP session ID, an
attacker could reuse a previously used session ID for further
requests. (CVE-2015-5346)

* A CSRF flaw was found in Tomcat's the index pages for the Manager
and Host Manager applications. These applications included a valid
CSRF token when issuing a redirect as a result of an unauthenticated
request to the root of the web application. This token could then be
used by an attacker to perform a CSRF attack. (CVE-2015-5351)

* It was found that several Tomcat session persistence mechanisms
could allow a remote, authenticated user to bypass intended
SecurityManager restrictions and execute arbitrary code in a
privileged context via a web application that placed a crafted object
in a session. (CVE-2016-0714)

* A security manager bypass flaw was found in Tomcat that could allow
remote, authenticated users to access arbitrary application data,
potentially resulting in a denial of service. (CVE-2016-0763)

* It was found that Tomcat could reveal the presence of a directory
even when that directory was protected by a security constraint. A
user could make a request to a directory via a URL not ending with a
slash and, depending on whether Tomcat redirected that request, could
confirm whether that directory existed. (CVE-2015-5345)

* It was found that Tomcat allowed the StatusManagerServlet to be
loaded by a web application when a security manager was configured.
This allowed a web application to list all deployed web applications
and expose sensitive information such as session IDs. (CVE-2016-0706)"
