Remediation/Fixes

The IBM Java Runtime Environment (JRE) shipped with IBM Spectrum Protect for Enterprise Resource Planing (ERP) on AIX and Linux may be affected by CVE-2020-27221. IBM Spectrum Protect for ERP ONLY uses the JRE duringinstallation and uninstallation of the product. During normal operation of IBM Spectrum for ERP, the JRE is not used. To make sure this vulnerability can not be exploited, the JRE should be deleted.

On AIX remove one of the following folders:

For DB2, remove /usr/tivoli/tsm/tdp_r3/db264/jre
For Oracle, remove /usr/tivoli/tsm/tdp_r3/ora64/jre

On Linux, remove one of the following folders:

For Db2, remove /opt/tivoli/tsm/tdp_r3/db264/jre
For SAP HANA, remove /opt/tivoli/tsm/tdp_hana/jre
For Oracle, remove /opt/tivoli/tsm/tdp_r3/ora64/jre

All backup and restore operations can continue without any impact. If you need to uninstall IBM Spectrum Protect for ERP, you must first install an IBM JRE at level 8.0.6.25 or higher as the system JRE. The uninstallation process can then be performed without any restrictions. Future updates of IBM Spectrum Protect for ERP will contain a JRE that is not affected by CVE-2020-27221.
