Affected Products and Versions

Rational Directory Server (Tivoli) v5.2.1 iFix 12 and earlier.

Rational Directory Administrator v6.0.0.2 iFix 06 and earlier.

Remediation/Fixes

1. Install one of the following IBM JREs supported versions that contain the fixes for these vulnerabilities:

• IBM Java Runtime Environment, Version 7 R1 Service Refresh 4 Fix Pack 5
• IBM Java Runtime Environment, Version 8 Service Refresh 4 Fix Pack 5

2. After installing a fixed IBM JRE version, install Rational Directory Server v5.2.1 iFix12 and Rational Directory Administrator v6.0.0.2 iFix06 from:

• Rational Directory Server (Tivoli) Interim Fix 12 for 5.2.1
• Rational Directory Administrator Interim Fix 06 for 6.0.0.2
  These steps will update the path of recommended/fixed IBM JRE in RDS/RDA.

For versions of Rational Directory Server that are earlier than version 5.2.1, and Rational Directory Administrator versions earlier than 6.0.0.2, IBM recommends upgrading to a fixed, supported version/release/platform of the product.
