Affected Products and Versions

All fix pack levels of IBM Db2 V9.7, V10.1, V10.5, V11.1 and V11.5 editions on all platforms are affected.

Remediation/Fixes

The recommended solution is to apply the appropriate fix for this vulnerability.

The fix for this vulnerability is in the latest version of IBM JDK. Customers running any vulnerable fixpack level of an affected Program, V10.1, V10.5, V11.1 or V11.5 can download the latest version of IBM JDK from Fix Central. At this point, a fix for V9.7 is not available.
 

Affected IBM SDK, Java Technology Edition, Version:

  • 7.0.10.45 and earlier
  • 7.1.4.45 and earlier
  • 8.0.5.37 and earlier
  • Earlier releases (6, 5.0, 1.4.2, 1.3.1, 1.2.2 etc.) may also be affected, but they are no longer supported.


Fixes for applicable vulnerabilities are included in IBM SDK, Java Technology Edition:

  • 7.0.10.50
  • 7.1.4.50
  • 8.0.5.40
HP is now shipping their JDK fixes twice a year, hence there is no fix available for HP-UX. The bulletin will be updated when it becomes available.

Refer to the table below to determine the IBM JDK level that contains the fix. Then follow the instructions below to perform the JDK installation.

Db2 Release Fixed IBM Release
V10.1.x 7.0.10.50 or later
