IBM Rational ClearCase uses the OpenSSL component for establishing SSL connections. ClearCase now ships an updated version of OpenSSL on Unix and Linux platforms, and uses a new component called IBM GSKit on Windows which also mitigates against the OpenSSL vulnerabilities.

Description: OpenSSL versions prior to 1.0.0 do not follow best security practices and need to be upgraded. For a complete list of OpenSSL Vulnerabilities by version, please refer to:
ClearCase 220.127.116.11 and 18.104.22.168 have been upgraded to ship with version 1.0.1C OpenSSL.
Prior versions of ClearCase shipped with OpenSSL version 0.9.7e.
On Windows platforms, ClearCase now uses the IBM GSKit component to perform SSL. IBM GSKit includes the OpenSSL security corrections.
The OpenSSL component is used by ClearCase for making SSL connections for OSLC-enabled UCM to ClearQuest. The OpenSSL component is also invoked if user supplied Perl code uses ratlperl to make SSL connections.
These vulnerabilities are not relevant for the traditional ClearCase to ClearQuest UCM integration.
Affected Products and Versions
Any supported platform.
Workarounds and Mitigations
Mitigation: Keep the SSL connections used for OSLC-enabled UCM between ClearCase and ClearQuest behind firewalls, and on your internal network.
