Affected Products and Versions
The following IBM Java versions are affected:
IBM SDK, Java Technology Edition, Version 7 Service Refresh 10 Fix Pack 45 and earlier releases
IBM SDK, Java Technology Edition, Version 7 R1 Service Refresh 4 Fix Pack 45 and earlier releases
IBM SDK, Java Technology Edition, Version 8 Service Refresh 5 Fix Pack 40 and earlier releases
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.
Remediation/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 Security Bulletin: Multiple vulnerabilities may affect IBM® SDK, Java™ Technology Edition 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 JavaTM Technology Security Alerts or referenced on Oracle’s latest Critical Patch Update (which can be accessed via developerWorks JavaTM 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 Fix Pack.
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.
