Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Upstream NVD CPE data marks all versions as affected. The upstream fix for issue #606 is included in libtiff 4.7.0; confirmed by the release notes, fixing commit ancestry, and Debian's tracker.
