Summary

An integer overflow exists in the FTS5 https://sqlite.org/fts5.html  extension. It occurs when the size of an array of tombstone pointers is calculated and truncated into a 32-bit integer. A pointer to partially controlled data can then be written out of bounds.

Fencer Intel 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: Added CPE configurations because not yet analyzed by NVD.
