Preface: The virtual table is created in the same SQLite database in wich the Core Data content resides. To keep this table as light as possible only object properties relevant to the search query are inserted.

Vulnerability details: A vulnerability in the rtreenode() function of SQLite3 could allow an unauthenticated, remote attacker to access sensitive information .
