Notes:

• If you use CCRC as an extension offering installed into an Eclipse shell (one not provided as part of a ClearCase release), you should update the Java™ Virtual Machine used by Eclipse to include a fix for CVE-2014-3566 and CVE-2014-6457. Contact the supplier of your Eclipse or Java™ Virtual Machine for instructions on updating Eclipse.

IBM recommends that you review your entire environment to identify areas that enable the SSLv3 protocol and take appropriate mitigation and remediation actions. The most immediate mitigation action that can be taken is disabling SSLv3. You should verify disabling SSLv3 does not cause any compatibility issues.
