Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUnspecified vulnerability in the XML Digital Signature verification functionality in JVA-RUN in JDK 6.0 in IBM OS/400 i5/OS V5R4M0 and V6R1M0 has unknown impact and attack vectors related to "XML SECURITY PATCH."
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply IBM PTF for Java XML Security (contact IBM for specific PTF number for your OS/400 i5/OS version)
- Access the IBM support document at http://www-01.ibm.com/support/docview.wss?uid=nas2741c96b7c573b81a862575cc003c726e to obtain the specific patch for your OS/400 version (V5R4M0 or V6R1M0)
- Identify the exact PTF (Program Temporary Fix) number from the IBM document for your IBM i5/OS version
- Apply the patch according to IBM's installation instructions for your specific OS version
- After applying the patch, verify the XML Digital Signature functionality works correctly in JVA-RUN
- Restart any affected Java applications using JVA-RUN to ensure the patch takes effect

- A config change or rule that shut the vector down
- A gotcha in the upgrade path that cost you an afternoon
