Affected Products and Versions

Affected Product(s)Version(s)
IBM InfoSphere Global Name Management6.0

Remediation/Fixes

Customers with IBM InfoSphere Global Name Management version 6.0 are encouraged to upgrade to version 7, which has no Name Analyzer web component and no log4j libraries.

For customers remaining on GNM version 6.0:
While a way has not been found to exploit this vulnerability in GNM 6, removal of the Name Analyzer web component removes all log4j libraries and all possibility of such an exploit. The Name Analyzer component is rarely if ever used in GNM 6.0, and in fact is no longer included in GNM 7.0, the current and recommended GNM release.

Remove the Name Analyzer component by following instructions in the technical note at https://www.ibm.com/support/pages/node/6526448 .

The web service capabilities of GNM are not affected by this vulnerability, and are unaffected by removal of Name Analyzer.
