Abstract

Fix Pack 3a for DB2 V9.5 is now available which includes fixes for some vulnerabilities. These fixes, where applicable, are also available in Fix Pack 6a for DB2 Version 9.1, and FixPak 17a for DB2 Universal Database™ (DB2 UDB) Version 8.1 (also known as FixPak 10 for DB2 UDB Version 8.2),

A set of vulnerabilities was discovered in some DB2 database products. These vulnerabilities were analyzed by the DB2 development organization and a set of corresponding fixes was created to address the reported issues. IBM DB2 development organization to addressed these vulnerabilities before they were made public. IBM is not currently aware of any externally reported incidents where production DB2 installations have been compromised due to these vulnerabilities.
The affected DB2 UDB for Linux, UNIX, and Windows Version 8.1 and 8.2, Version 9.1 and Version 9.5 products are:

  • DB2 Enterprise Server Edition
  • DB2 Workgroup Server (all Editions)
  • DB2 Express Server (all Editions)
  • DB2 Personal Edition
  • DB2 Connect Server (all Editions)

DB2 Client component and DB2 products or components other than those listed above are not affected.

Due to the complexity of the fixes required to eliminate the reported service vulnerabilities, it is not feasible to retrofit the same fixes into earlier DB2 UDB Version 8 and DB2 Version 9 fix packs, including all of the special builds of the above DB2 database products that precede DB2 UDB Version 8.1 FixPak 17a, DB2 Version 9.1 Fix Pack 6a and DB2 Version 9.5 Fix Pack 3.

The specifics of the Security APARs incorporated into the above DB2 fix packs can be found in the following table:
