AFFECTED PRODUCTS:
- - IBM Initiate Master Data Service versions 9.5, and 9.7
- - IBM InfoSphere Master Data Management Standard Edition versions 10.0 and 10.1
REMEDIATION:
Fixes:
Important Limitation:
Resolution of the vulnerabilities in this security bulletin is accomplished by
installing and using a later version of OpenSSL. On AIX, and on AIX only, the
current version of OpenSSL has known breaking issues in TLS when FIPS mode is
enabled. Based on this, FIPS mode is disabled when the version of OpenSSL
included in the fixes below is installed for use by brokers on AIX. No change
is made to the current configuration of FIPS mode for OpenSSL when installing
the fixes below on any other operating system.
An attempt to enable FIPS mode for OpenSSL on AIX after installing the fixes
below will result in a FIPS fingerprint error in the broker logs.
For IBM Initiate Master Data Service version 9.5.
- - Install "September 2013 Fix Pack for v9.5 MDS"
For IBM Initiate Master Data Service version 9.7.
- - Install "September 2013 Fix Pack for v9.7 MDS"
For IBM InfoSphere Master Data Management Standard Edition version10.0
- - Install "September 2013 Fix Pack for v10.0 MDS"
For IBM InfoSphere Master Data Management Standard Edition version 10.1
- - Install "September 2013 Fix Pack for v10.1 MDS"
Workaround(s) & Mitigation(s): None known.
