• 6.3.0.0 through 6.3.5.x
• 6.2, 6.1, and 5.5 all levels (these releases are EOS)

Remediation/Fixes

This security exposure occurs only at installation time and does not affect an already installed Tivoli Monitoring for Tivoli Storage Manger, whether it was installed manually or via auto-deployment.

If you are not installing a fixed level of the IBM Tivoli Monitoring for Tivoli Storage Manager (6.3.6) or an unaffected level (7.1 or higher), then the installation package is vulnerable to this security issue during installation and you must use the workaround provided below to prevent being exposed to the vulnerability.

Workarounds and Mitigations

This security exposure occurs only at installation time and does not affect an already installed Tivoli Monitoring for Tivoli Storage Manager, whether it was installed manually or via auto-deployment.

To prevent exposure to this security vulnerability, download and run the installation package from a clean directory using the following steps:

1. As an administrator, create a new secure directory. The directory must not exist before and only the administrator should have write permission to it.
2. Unzip or copy the files from your installation media into this new directory.
3. Run the installation exe from this directory to install the product. Proceed with the installation as normal.

If installation of a Tivoli Monitoring for Tivoli Storage Manager package below the fixing level (6.3.6) or installation of a package for 6.2 or below is required, then the above workaround should be used to avoid exposure to this vulnerability during the installation process. The workaround is not needed if the fixing level of 6.3.6 or a higher level of the package is installed.
