The recommended solution is to apply the iFixes provided by IBM as outlined here.

Vendor Fix(es):

For IBM RLKS 812 or RLKS 8.1.1 Users

An iFix is available to address this vulnerability. Links for downloading the fixes and the installation instructions are listed below.

RLKS 812 iFix 02
RLKS 811 iFix 06

How to install the iFixes

To install the Rational License Key Server fix on Windows platforms:
1. Download the Windows file.
2. Extract the compressed files to an appropriate directory.
3. Add the iFix repository location in Installation Manager as follows:

    a) Launch IBM Installation Manager.
    b) Click File->Preferences->Repositories.
    c) Click Add Repository.
    d) Browse to or enter the file path to the repository.config file. The repository.config file is located in the sub-directory "ifix" where you extracted the compressed files.
4. Stop the Rational License Key Server before installing the iFix.
Ensure the following processes are not running - lmgrd, lmutil, lmtools and ibmratl.
5. On the main page of Installation Manager click, Update.
6. Follow the instructions to install the iFix.
7. Start the Rational License Key Server.

To install the Rational License Key Server fix on Unix platforms:
1. Download the iFix.tar file for the platform.
2. Extract the iFix.tar: tar -xvf <iFix>.tar.
Use GNU tar for the extraction as the long names in the JRE directory cannot be handled by the native tars.
3. Go to the installation location of the license server.
4. Navigate to the config sub-folder.
5. Run the start_lmgrd_on_this_host script file with the stop option: ./start_lmgrd_on_this_host stop
6. The license server stops. To verify, run the command: ps -ef | grep lmgrd
7. Navigate to sub-directory <installation_directory>/base/cots/flexlm.11.8/<Platform>
8. Overwrite files in this directory with all the files from the iFix.
9. Navigate to the sub-directory <installation_directory>/config/jrexxx.<platform> or <installation_directory>/config/jre142.<platform>/jre. The JRE version can be either 1.4.2 or 1.5.0.
10. Delete the directories named "bin", "lib", "plugin" and "javaws" wherever applicable.
11. Copy the diretories named named "bin", "lib", "plugin" and "javaws" from the iFix wherever applicable.
12. Navigate to the sub-directory <installation_directory>/config/migrationutility.
13. Replace the file named "" from the iFix.
14. Go to the <installation_directory>/config/ directory.
15. Start the license server using the command: ./start_lmgrd_on_this_host start

Note:- The iFix can also be used as a complete, standalone installer on Unix platforms.

For IBM RLS 8.x, RLS 7.x and IBM Telelogic License Server 2.0 Users

There are no plans to release fixes for Rational License Server v8.x, v7.x and Telelogic License Server 2.0. IBM recommends all customers using these versions of license servers migrate to IBM Rational License Key server 8.1.2 and update the IBM Rational License Key server 8.1.2 with the fix for the security vulnerability described in this Technote.

Instructions on migrating to RLKS 8.1.2 are available through this Info Center Link.

Migration to RLKS 8.1.2

RLKS 8.1.2 can be downloaded from your Passport Advantage account or here
