Security Bulletin

Summary

IBM Tivoli Storage FlashCopy Manager (FCM) is shipped as a component of IBM
Db2. Information about security vulnerabilities affecting IBM Tivoli Storage
FCM has been published in a security bulletin.

Vulnerability Details

Please consult the security bulletin
"Vulnerabilities in OpenSSL affect Tivoli Storage FlashCopy Manager Unix"
for vulnerability details.




Affected Products and Versions

IBM Db2 Advanced Copy Services included in IBM Db2 and Db2 Connect v10.1,
v10.5 and v11.1 server editions running on AIX and Linux are affected.

Only users of DB2 Advanced Copy Services (snapshot backup) are affected by
this vulnerability. IBM Db2 includes a restricted version of IBM Tivoli
Storage FlashCopy Manager, i.e. FCM v3.2 and v4.1, and both versions are
affected by this vulnerability. IBM Db2 Advanced Copy Services in conjunction
with IBM Tivoli Storage FCM 3.2 or 4.1, on all current fix packs of IBM Db2
v10.1, v10.5 and v11.1, are affected. AIX installations of Db2 may have this
package installed by default, though it may not be in use on the system. FCM
is not automatically installed on Linux and neither platforms for IBM Db2
v11.1. IBM Db2 v11.1 uses FCM v4.1 and older version of IBM Db2 uses FCM
v3.2.

Remediation/Fixes

If you use Db2 Advanced Copy Services (snapshot backup) with the restricted
version of FCM included with Db2, then obtain the updated and remediated
restricted version of FCM (v.4 1). Note: The fix is only available for FCM
v4.1. The updated package allow users to upgrade their restricted FCM v3.2 to
restricted FCM v4.1.

The FCM package containing the fix For Db2 v11.1 can be found in
Passport Advantage

+----------+------------------------------------------------------------------+


The FCM packages for Db2 v10.5 can be used with both Db2 v10.1 and Db2 v10.5 on
any fix pack.

Please note that for the AIX platform, Db2 v10.1 and Db2 v10.5 up to FP8,
installing the fixpack will overwrite the FCM in sqllib/acs with a vulnerable
version of FCM. You need to reapply the FCM fix after each fixpack update. As
of Db2 v10.5 FP9, fixpack updates will remove all files under the directory
sqllib/acs. You will need to install the latest FCM after each fixpack update.

For installation instructions, please follow the documentation provided within
the IBM Db2 information center:
