Security Bulletin: Multiple vulnerabilities in IBM Java Runtime affect Rational License Key Server Administration and Reporting Tool (CVE-2015-0138, CVE-2014-3566, CVE-2014-6593, )

Summary

There are multiple vulnerabilities in IBM® Runtime Environment Java™ Technology Edition, Version 6.0.16.2 that is used by Rational License Key Server Administration and Reporting Tool. These issues were disclosed as part of the IBM Java SDK updates in January 2015. This bulletin also addresses the “FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability.

Vulnerability Details

CVEID: CVE-2015-0138

DESCRIPTION: A vulnerability in various IBM SSL/TLS implementations could allow a remote attacker to downgrade the security of certain SSL/TLS connections. An IBM SSL/TLS client implementation could accept the use of an RSA temporary key in a non-export RSA key exchange ciphersuite. This could allow a remote attacker using man-in-the-middle techniques to facilitate brute-force decryption of TLS/SSL traffic between vulnerable clients and servers.

This vulnerability is also known as the FREAK attack.

CVEID: CVE-2014-3566

DESCRIPTION: Multiple products could allow a remote attacker to obtain sensitive information, caused by a design error when using the SSLv3 protocol. A remote user with the ability to conduct a man-in-the-middle attack could exploit this vulnerability via the POODLE (Padding Oracle On Downgraded Legacy Encryption) attack to decrypt SSL sessions and calculate the plaintext of secure connections.

Remediation/Fixes

Replace the JRE used in IBM RLKS Administration and Reporting Tool and IBM RLKS Administration Agent.

Steps to replace the JRE in IBM RLKS Administration and Reporting Tool (All Versions)

1. Go to Fix Central

2. On the Find product tab, enter Rational Common Licensing in theProduct Selector field and hit enter.

3. Select the Installed Version and hit continue button.

4. Select the platform of the machine where RLKS Administration and Reporting Tool is installed and hit continue button.

5. On the Identify fixes page, selectBrowse for fixesand selectShow fixes that apply to this version and hit continue button.

6. Download the Java runtime iFix for RLKS Administration and Reporting Tool.
**
Note:Although the name of the iFix isRLKS_Administration_And_Reporting_Tool_8146_Admin_iFix_1_<Platform>_<Architecture>**, the same ifix is applicable to all previous RLKS Administration and Reporting Tool versions.

7. Shutdown RLKS Administration and Reporting Tool.

8. Go to the installation location of RLKS Administration and Reporting Tool.

9. Rename <install location>/server/jre folder to <install location>/server/jre_back.
This step backs up the existing JRE.

10. Extract the downloaded JRE into <install location>/server/ folder

Example: <install location>/server/jre

11. Startup RLKS Administration and Reporting Tool.

12. Login to the tool using rcladmin user and verify that you see the configured license servers under ‘Server’ tab.
