Security and HIPER APARs fixed in DB2 for Linux, UNIX, and Windows Version 9.5 Fix Pack 4

Flash (Alert)


Abstract

Fix Pack 4 for DB2 V9.5 is now available which includes fixes for some security vulnerabilities and HIPER APARs. These fixes, where applicable, are also available in Fix Pack 18 for DB2 Version 8, Fix Pack 8 for DB2 Version 9.1 and Fix Pack 1 for DB2 Version 9.7.

IBM® recommends that you review the APAR descriptions and deploy one of the above fix packs to correct them on your affected DB2 installations.

Content

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 is not currently aware of any externally reported incidents where production DB2 installations have been compromised due to these issues.

The affected DB2 for Linux, UNIX, and Windows 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 issues, it is not feasible to retrofit the same fixes into earlier DB2 UDB Version 8, DB2 Version 9.1 and DB2 Version 9.5 fix packs.

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