In reply to Charles Warren III.

Hi Charles--thanks for reaching out. The IOS Software Checker should be providing this information; it's the single source of truth for affected and fixed software data. The final screen should clearly identify which advisories affect the release you queried against, and the first release in the upgrade path that addresses all vulnerabilities in that document should be listed in the 'First Fixed' column. If your query identified more than one Security Advisory that affects your release(s), the tool should also provide a combined first fixed release that addressed all vulnerabilities in all documents. Please let us know if the tool isn't functioning as intended.
