Synopsis :

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

Description :

An update is now available for Red Hat JBoss Enterprise Web Server 2.1
for RHEL 7.

Red Hat Product Security has rated this update as having a security
impact of Important. 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 serves as a replacement for Red Hat JBoss Web Server
2.1.0, and includes several bug fixes. Refer to the Red Hat JBoss Web
Server 2.1.1 Release Notes for information on the most significant of
these changes, available shortly from
https://access.redhat.com/site/documentation/

All users of Red Hat JBoss Web Server 2.1.0 on Red Hat Enterprise
Linux 7 are advised to upgrade to Red Hat JBoss Web Server 2.1.1. The
JBoss server process must be restarted for this update to take effect.

Security Fix(es) :

* It was discovered that httpd used the value of the Proxy header from
HTTP requests to initialize the HTTP_PROXY environment variable for
CGI scripts, which in turn was incorrectly used by certain HTTP client
implementations to configure the proxy for outgoing HTTP requests. A
remote attacker could possibly use this flaw to redirect HTTP requests
performed by a CGI script to an attacker-controlled proxy via a
malicious HTTP request. (CVE-2016-5387)

* An integer overflow flaw, leading to a buffer overflow, was found in
the way the EVP_EncodeUpdate() function of OpenSSL parsed very large
amounts of input data. A remote attacker could use this flaw to crash
an application using OpenSSL or, possibly, execute arbitrary code with
the permissions of the user running that application. (CVE-2016-2105)

* An integer overflow flaw, leading to a buffer overflow, was found in
the way the EVP_EncryptUpdate() function of OpenSSL parsed very large
amounts of input data. A remote attacker could use this flaw to crash
an application using OpenSSL or, possibly, execute arbitrary code with
the permissions of the user running that application. (CVE-2016-2106)

* It was discovered that it is possible to remotely Segfault Apache
http server with a specially crafted string sent to the mod_cluster
via service messages (MCMP). (CVE-2016-3110)

Red Hat would like to thank Scott Geary (VendHQ) for reporting
