Affected Products and Versions

2. 6.0.0.3

Remediation/Fixes

Note: For remediating these vulnerabilities, IBM® recommends upgrading Rational Directory Administrator to 6.0.0.2 or later.

1. Download the following IBM JRE version that contain the fixes for these vulnerabilities:

2. After downloading a fixed IBM JRE version, refer the following technote for JRE upgrade instructions:

Note:

To improve the robustness of LDAPS (secure LDAP over TLS) connections, endpoint identification algorithms have been enabled by default. There may be situations where some applications that were previously able to successfully connect to an LDAPS server may no longer be able to do so.
With this LDAP update, LDAP is asking JSSE to validate the LDAP server’s certificate to ensure it is compliant with hostname verification. With this change, if the server’s certificate is not compliant, then exception will be thrown. In the past, LDAP did not request JSSE to perform hostname verification and a non-compliant server certificate would not have had caused an issue.
In order to resolve the issue, Regenerate the RDS server certificate(tdsserverkey.kdb) so that the certificate’s subject name or certificate’s subject alternate name matches the RDS server hostname, by following instructions from technote:

How can I generate my own ‘tdsserverkey.kdb’ keystore for TLSv12 communication and use it in a IBM Rational Directory Server (Tivoli) deployment?

After regenerating the RDS Server certificate matching with the RDS Server Hostname, use FQDN’s wherever applicable.
E.g. : RDA Login Screen, Creating RDS Partition and DOORS to RDS Connection.

(If you have already regenerated the RDS Server certificate by following above technote, while upgrading to IBM JRE versions 7.1.4.30 or later or 8.0.5.20 or later, then no need to follow the technote again)

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.

If you run your own Java code using the IBM Java Runtime delivered with this product, you should evaluate your code to determine whether additional Java vulnerabilities are applicable to your code.
