Synopsis :

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

Description :

Red Hat JBoss Web Server 2.0.1, which fixes multiple security issues
and several bugs, is now available for Red Hat Enterprise Linux 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.

This release serves as a replacement for Red Hat JBoss Web Server
2.0.0, and includes several bug fixes. Refer to the Red Hat JBoss Web
Server 2.0.1 Release Notes for information on the most significant of
these changes, available shortly from
https://access.redhat.com/site/documentation/

The following security issues are also fixed with this release :

Cross-site scripting (XSS) flaws were found in the Apache HTTP Server
mod_proxy_balancer module's manager web interface. If a remote
attacker could trick a user, who was logged into the manager web
interface, into visiting a specially crafted URL, it would lead to
arbitrary web script execution in the context of the user's manager
interface session. (CVE-2012-4558)

Cross-site scripting (XSS) flaws were found in the Apache HTTP Server
mod_info, mod_status, mod_imagemap, mod_ldap, and mod_proxy_ftp
modules. An attacker could possibly use these flaws to perform XSS
attacks if they were able to make the victim's browser generate an
HTTP request with a specially crafted Host header. (CVE-2012-3499)

A session fixation flaw was found in the Tomcat FormAuthenticator
module. During a narrow window of time, if a remote attacker sent
requests while a user was logging in, it could possibly result in the
attacker's requests being processed as if they were sent by the user.
(CVE-2013-2067)

A denial of service flaw was found in the way the Tomcat chunked
transfer encoding input filter processed CRLF sequences. A remote
attacker could use this flaw to send an excessively long request,
consuming network bandwidth, CPU, and memory on the Tomcat server.
Chunked transfer encoding is enabled by default. (CVE-2012-3544)

A flaw was found in the way the Tomcat 7 asynchronous context
implementation performed request management in certain circumstances.
If an application used AsyncListeners and threw RuntimeExceptions,
Tomcat could send a reply that contains information from a different
user's request, possibly leading to the disclosure of sensitive
information. This issue only affected Tomcat 7. (CVE-2013-2071)

Note: Do not install Red Hat JBoss Web Server 2 on a host which has
Red Hat JBoss Web Server 1 installed.

Warning: Before applying the update, back up your existing Red Hat
JBoss Web Server installation (including all applications and
configuration files).

All users of Red Hat JBoss Web Server 2.0.0 on Red Hat Enterprise
Linux 6 are advised to upgrade to Red Hat JBoss Web Server 2.0.1. The
JBoss server process must be restarted for this update to take effect.
