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.
| Package Name | Part Number |
| IBM FlashCopy Limited function for xLinux and AIX SDK V1.0 for AIX Multilingual | CNLN8ML |
| IBM FlashCopy Limited function for xLinux SDK V1.0 for Linux on AMD64 and Intel EM64T systems (x64) Multilingual | CNLN9ML |
The FCM package containing the fix For Db2 v10.5 can be found in Fix Central for v10.5 by searching for the keyword FCM.
| Platform | Description |
| AIX | Db2 10.5 Fix Pack 9 for AIX (64 bit), Aix distros for FCM |
| Linux | Db2 10.5 Fix Pack 9 for Linux/x86-64 (64 bit), Linux distros for FCM |
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.
