This document contains a list of fixes for HIPER APARs in DB2 Version 9.5 Fix Pack 9
IBM® recommends that you review the APAR descriptions and deploy one of the above fix packs to correct them on your affected DB2 installations.
A set of HIPER APARs were discovered in some DB2 database products. These APARs were analysed 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 UDB 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 Version 9.5 fix packs.
The specifics of the Security APARs incorporated into the above DB2 fix packs can be found in the following table:
|IC76899||SECURITY: REMOTE DENIAL OF SERVICE OF DB2 SERVER.|
|IC79970||SECURITY: DB2 ESCALATION OF PRIVILEGE VULNERABILITY.|
|IC80728||SECURITY: Remote Escalation of Privilege Vulnerability in DAS.|
|IC81379||Security: Denial of Service Security Vulnerability in DB2's XML Feature.|
|IC81387||SECURITY: UNAUTHORIZED ACCESS TO TABLES.|
In addition to the Security APARs, here is a list of HIPER APARs included in these fix packs of which you should be aware.
