Security Bulletin
Summary
The “FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability affects IBM® SDK Java™ Technology Edition, Version 6.0.16.2, that is used by Rational Lifecycle Integration Adapter for HP ALM.
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.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/#/vulnerabilities/100691 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
Affected Products and Versions
IBM Rational Lifecycle Integration Adapter for HP ALM 1.2 and later versions
Remediation/Fixes
The fix is available on Fix Central.
You should verify that applying this fix does not cause any compatibility issues.
To update IBM Rational Lifecycle Integration Adapter with a corrected JRE, follow the instructions below. Depending on how you deployed the products, and depending on your usage scenarios, you might need to upgrade the IBM SDK, Java Technology Edition in IBM WebSphere Application Server and Apache Tomcat. Be sure to upgrade all the components that you use in your deployment uses.
NOTE: IBM SDK, Java Technology Edition is only included in IBM Rational Lifecycle Integration Adapter version 1.1.2 or later. Previous versions of the Rational Lifecycle Integration Adapter Standard Edition HP Adapter were released as WAR files only. Please consult with the application server documentation for updating the IBM SDK, Java Technology Edition.
Upgrading the JRE for a WebSphere Application Server installation
If your products are deployed on WebSphere Application Server, Java SDK Upgrade Policy for the IBM WebSphere Application Server lists IBM SDK, Java Technology Edition upgrades that are available. Also check the Product Security Incident Response Blog for any recent security bulletins for WebSphere Application Server that may have fixpacks or interim fixes for the JRE.
Upgrading the IBM SDK, Java Technology Edition for a Tomcat installations
1. Stop the Rational Lifecycle Integration Adapter server.
Note: The applications may be running in different application server instances or using a delegated converter.
2. Go to the original installation directory, and rename the /jre folder
<InstallDir>/server/jre
to
<InstallDir>/server/jre-Original
This ensures that the original JRE is kept as a backup in the event a restore is required.
Example (Linux):
mv <OrigInstallDir>/server/jre <OrigInstallDir>/server/jre-Original
3. Extract the new JRE archive provided by support to the Installation directory.
Example (Linux):
unzip <newInsallZip> -d <InstallDir>/server/
4. Remove the Apache Tomcat temporary files in the following directories:
<OrigInstallDir>/server/tomcat/temp
<OrigInstallDir>/server/tomcat/work/Catalina/localhost
5. Restart the Rational Lifecycle Integration Adapter server
