The Logjam Attack on TLS connections using the Diffie-Hellman (DH) key exchange protocol affects IBM Rational ClearQuest.
CVEID: CVE-2015-4000**
DESCRIPTION:** The TLS protocol could allow a remote attacker to obtain sensitive information, caused by the failure to properly convey a DHE_EXPORT ciphersuite choice. An attacker could exploit this vulnerability using man-in-the-middle techniques to force a downgrade to 512-bit export-grade cipher. Successful exploitation could allow an attacker to recover the session key as well as modify the contents of the traffic. This vulnerability is commonly referred to as “Logjam”.

IBM Rational ClearQuest, versions 7.1.0.x, 7.1.1.x, 7.1.2.x, 8.0.0.x, 8.0.1.x, in the following components:
Affected Versions
|
** Applying the fix**
—|—
8.0.1 through 8.0.1.9
| Install Rational ClearQuest Fix Pack 10 (8.0.1.10) for 8.0.1.
8.0 through 8.0.0.16
| Install Rational ClearQuest Fix Pack 17 (8.0.0.17) for 8.0.
7.1.2 through 7.1.2.17
| Customers on extended support contracts should install Rational ClearQuest Fix Pack 19 (7.1.2.19) for 7.1.2. If you enable SSL for your Oracle database, see the “Workarounds and Mitigations” section below.
7.1.1.x (all fix packs)
7.1.0.x (all fix packs)
| Customers on extended support contracts should contact Rational Customer Support
You should verify applying this configuration change does not cause any compatibility issues. If you change the default setting after applying the fix, you will expose yourself to the attack described above. IBM recommends that you review your entire environment to identify other areas where you have enabled the Diffie-Hellman key-exchange protocol used in TLS and take appropriate mitigation and remediation actions.
For unsupported versions, IBM recommends upgrading to a fixed, supported version/release/platform of the product.
If you are not upgrading to ClearQuest Fix Pack 17 for 8.0 or ClearQuest Fix Pack 10 for 8.0.1, and you enable SSL for your Oracle database, then you will need to take further steps to mitigate the issue.
