Type/Severity

Security Advisory Important

Topic

An update for the openssl component for Red Hat JBoss Web Server 2.0.1 that fixes one security issue is now available from the Red Hat Customer Portal.

The Red Hat Security Response Team has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Description

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.

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library.

It was found that OpenSSL clients and servers could be forced, via a specially crafted handshake packet, to use weak keying material for communication. A man-in-the-middle attacker could use this flaw to decrypt and modify traffic between a client and a server. (CVE-2014-0224)

Note: In order to exploit this flaw, both the server and the client must be using a vulnerable version of OpenSSL; the server must be using OpenSSL version 1.0.1 and above, and the client must be using any version of OpenSSL. Red Hat JBoss Web Server includes OpenSSL 0.9.8e, so this flaw is only exploitable when OpenSSL in JBoss Web Server is used as a client, communicating with a vulnerable server running OpenSSL version 1.0.1 and above. For more information about this flaw, refer to: https://access.redhat.com/site/articles/904433

Red Hat would like to thank the OpenSSL project for reporting this issue. Upstream acknowledges KIKUCHI Masashi of Lepidum as the original reporter of this issue.

All users of Red Hat JBoss Web Server 2.0.1 as provided from the Red Hat Customer Portal are advised to apply this update. The Red Hat JBoss Web Server process must be restarted for the update to take effect.
