Summary
sqlite3 provides Ruby bindings for the SQLite3 embedded database. In version 2.9.4 and earlier, redefining a SQLite function with a different arity frees the previously registered function handler while SQLite may still reference it, resulting in a use-after-free. This issue is fixed in version 2.9.5.
