Affected

Not all deployments of Rational ClearQuest use OpenSSL in a way that is affected by these vulnerabilities.

You are vulnerable if your use of Rational ClearQuest includes any of these configurations:

1. You use SSL connections in perl scripts run by ratlperl or cqperl, or by ClearQuest hooks. In this situation, you should review all the fixes provided by the OpenSSL project to see which ones apply to your use of OpenSSL. See the references link below.
2. You integrate with ClearCase. See Security Bulletin: Vulnerability in OpenSSL affects IBM Rational ClearCase (CVE-2016-2107)
3. You connect to a ClearQuest database using SSL.

Remediation/Fixes

Apply a fix pack as listed in the table below. The fix pack includes OpenSSL 1.0.2h.
