Remediation/Fixes

In order to fix these vulnerabilities, Spring is to be upgraded to 5.3.26 version. The efix to resolve these vulnerabilities can only be applied to TADDM version 7.3.0.9 or later versions as per below given detailed steps. For customer at older TADDM Fixpack level (i.e., 7.3.0.8 or older), they need to first upgrade their TADDM environment to TADDM 7.3.0.9 level and then follow the step given below.

Detailed steps:

For TADDM 7.3.0.9 & Above, check if there is any previously applied eFixes in their TADDM environment.

  1.  If there is no prior efixes(ls -rlt etc/efix*) applied in their TADDM, then download the efix given in Table-1 and apply the efix.
  2. If there are existing efixes on TADDM (ls -rlt etc/efix*), please contact IBM Support and open a case for a custom version of the eFix as the efix involves TADDM code changes. Include the current eFix level (ls -rlt etc/efix*), TADDM version and a link to this bulletin in the Support Case

For any other TADDM fixpack level (i.e., 7.3.0.8 or older), to apply this bulletin, upgrade to TADDM 7.3.0.9 and then follow procedure as mentioned above for TADDM 7.3.0.9 & above .

Disclaimer

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
