Summary
An Apache Commons Collections vulnerability for handling Java object deserialization was addressed by IBM® DB2 Web Query for i. Apache is the underlying infrastructure for many java based products, including Web Query. While not part of Web Query itself, it was important to include the patch in Web Query updates. The following Web Query versions included the Apache vulnerability, but only for the specified group PTF levels:
Web Query 2.1.0 – group PTF levels 8, 10, 11, and 12.
Web Query 2.1.1 – group PTF level 1
The Web Query version 2.1.0 group PTF numbers for the respective version of the IBM i operating system are:
Release 6.1 – SF99646
Release 7.1 – SF99647
Release 7.2 – SF99747
The Web Query version 2.1.1 group PTF numbers are:
Release 6.1 – SF99656
Release 7.1 – SF99657
Release 7.2 – SF99658
