**DESCRIPTION:**Customers who have Java based applications, such as Maximo Asset Management, Maximo Asset Management Essentials, Maximo Asset Management for Energy Optimization, Maximo Industry Solutions (including Maximo for Government, Maximo for Nuclear Power, Maximo for Transportation, Maximo for Life Sciences, Maximo for Oil and Gas and Maximo for Utilities), Tivoli Asset Management for IT, Tivoli Service Request Manager, Maximo Service Desk, Change and Configuration Management Database, SmartCloud Control Desk, Intelligent Building Management, or TRIRIGA for Energy Optimization are potentially impacted by these vulnerabilities, which can cause issues related to confidentiality, integrity, and availability. For additional information including the most current description and CVSS for each vulnerability, please refer to developerWorks Java__TM_ Technology Security Alerts_.

There are a number of vulnerabilities in the IBM SDK, Java Technology Edition that affect various components. CVE-2013-5456, CVE-2013-5457 and CVE-2013-5458 allow code running under a security manager to escalate its privileges by modifying or removing the security manager. CVE-2013-4041 and CVE-2013-5375 allow code running under a security manager to access restricted classes. These vulnerabilities could occur when untrusted code is executed under a security manager, or when the IBM SDK, Java Technology Edition has been associated with a web browser for running applets and Web Start applications.

CVE-2013-5372 is a denial of service vulnerability which could result in a complete availability impact on the affected system.

This bulletin also covers all applicable CVEs published by Oracle as part of their October 2013 Java SE Critical Patch Update. For more information please refer to Oracle’s October 2013 Java SE CPU Advisory.

The developerWorks Java__TM_ Technology Security Alerts_ includes a link to Oracle’s October 2013 Critical Patch Update.

Affected Products and Versions

The following IBM Java versions are affected:
· IBM SDK Java Technology Edition Version 7***

· IBM SDK Java Technology Edition Version 6

· IBM SDK Java Technology Edition Version 5

· IBM SDK Java Technology Edition Version 1.4.2

Note that the following Oracle Java versions, which are not IBM products, are affected: Java SE JDK and JRE Version 7 Update 7 and earlier, Java SE JDK and JRE Version 6 Update 35 and earlier, Java SEJDK and JRE Version 5 Update 36 and earlier, and Java SE JDK and JRE Version 1.4.2_38 and earlier.

IBM supplied the Java Runtime Environment (JRE) from the IBM SDK Java Technology Edition Versions with the following:

The 7.1.x versions of Maximo Asset Management, Maximo Asset Management Essentials, Maximo Asset Management for Energy Optimization, Maximo for Government, Maximo for Nuclear Power, Maximo for Transportation, Maximo for Life Sciences, Maximo for Oil and Gas, Maximo for Utilities, Tivoli Asset Management for IT, Tivoli Service Request Manager, and Tivoli Change and Configuration Management Database bundled the JRE from IBM SDK Java Technology Edition Version 5.

The 7.2.x versions of Tivoli Asset Management for IT, Tivoli Service Request Manager, and Tivoli Change and Configuration Management Database bundled the JRE from IBM SDK Java Technology Edition Version 5.

The 7.5.x versions of Maximo Asset Management, Maximo Asset Management Essentials, Maximo for Government, Maximo for Nuclear Power, Maximo for Transportation, Maximo for Life Sciences, Maximo for Oil and Gas, Maximo for Utilities, and SmartCloud Control Desk bundled the JRE from IBM SDK Java Technology Edition Version 6.

Intelligent Building Management 1.1.x and TRIRIGA for Energy Optimization 1.1.x bundled the JRE from IBM SDK Java Technology Edition Version 6.

It is likely that earlier unsupported versions are also affected by these vulnerabilities. Remediation is not provided for product versions that are no longer supported. IBM recommends that customers running unsupported versions upgrade to the latest supported version of products in order to obtain remediation for the vulnerabilities.

***Please note that the versions of the IBM products listed above do not bundle JRE Version 7 or IBM SDK Java Technology Edition Version 7; however, JRE Version 7 and IBM SDK Java Technology Edition Version 7 are listed here because JRE Version 7 is prevalent on the browser and therefore can potentially impact access to these IBM product versions

Remediation/Fixes

_VENDOR FIXES: _
There are two areas where the vulnerabilities in the Java SDK/JDK or JRE may require remediation:
1. Application Server – Update the Websphere Application Server. Refer to JDK Fixes for Websphere Application Server for additional information on updating and maintaining the JDK component within Websphere. Customers with Oracle Weblogic Server, which is not an IBM product and is not shipped by IBM, will also want to update their server.
2. Browser Client - Update the Java plug-in used by the browser on client systems, using the remediated JRE version referenced on developerWorks Java__TM_ Technology Security Alerts_ or referenced on Oracle’s latest Critical Patch Update (which can be accessed via developerWorks Java__TM_ Technology Security Alerts_). Updating the browser Java plug-in may impact some applets such as Maximo Asset Management Scheduler. Download from IBM FixCentral the latest Maximo Asset Management Scheduler Interim Fix for Version 7.1 or the latest Maximo Asset Management Fix Pack for Version 7.5, which includes the resolution for APAR IV11560.

Due to the threat posed by a successful attack, IBM strongly recommends that customers apply fixes as soon as possible.

Workarounds and Mitigations

Until you apply the fixes, it may be possible to reduce the risk of successful attack by restricting network protocols required by an attack. For attacks that require certain privileges or access to certain packages, removing the privileges or the ability to access the packages from unprivileged users may help reduce the risk of successful attack. Both approaches may break application functionality, so IBM strongly recommends that customers test changes on non-production systems. Neither approach should be considered a long-term solution as neither corrects the underlying problem.
