Synopsis :

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

Description :

Red Hat JBoss Web Server 2.1.0, which fixes multiple security issues
and several bugs, is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Important
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
2.0.1, and includes several bug fixes. Refer to the Red Hat JBoss Web
Server 2.1.0 Release Notes, linked to in the References section, for
information on the most significant of these changes.

The following security issues are also fixed with this release :

A race condition flaw, leading to heap-based buffer overflows, was
found in the mod_status httpd module. A remote attacker able to access
a status page served by mod_status on a server using a threaded
Multi-Processing Module (MPM) could send a specially crafted request
that would cause the httpd child process to crash or, possibly, allow
the attacker to execute arbitrary code with the privileges of the
'apache' user. (CVE-2014-0226)

A denial of service flaw was found in the way httpd's mod_deflate
module handled request body decompression (configured via the
'DEFLATE' input filter). A remote attacker able to send a request
whose body would be decompressed could use this flaw to consume an
excessive amount of system memory and CPU on the target system.

A denial of service flaw was found in the way httpd's mod_cgid module
executed CGI scripts that did not read data from the standard input. A
remote attacker could submit a specially crafted request that would
cause the httpd child process to hang indefinitely. (CVE-2014-0231)

It was found that several application-provided XML files, such as
web.xml, content.xml, *.tld, *.tagx, and *.jspx, resolved external
entities, permitting XML External Entity (XXE) attacks. An attacker
able to deploy malicious applications to Tomcat could use this flaw to
circumvent security restrictions set by the JSM, and gain access to
sensitive information on the system. Note that this flaw only affected
deployments in which Tomcat is running applications from untrusted
sources, such as in a shared hosting environment. (CVE-2013-4590)

It was found that, in certain circumstances, it was possible for a
malicious web application to replace the XML parsers used by Tomcat to
process XSLTs for the default servlet, JSP documents, tag library
descriptors (TLDs), and tag plug-in configuration files. The injected
XML parser(s) could then bypass the limits imposed on XML external
entities and/or gain access to the XML files processed for other web
applications deployed on the same Tomcat instance. (CVE-2014-0119)

All users of Red Hat JBoss Web Server 2.0.1 on Red Hat Enterprise
Linux 6 are advised to upgrade to Red Hat JBoss Web Server 2.1.0. The
JBoss server process must be restarted for this update to take effect.
