The PRAGMA integrity_check command might cause the byte-code for a prepared statement to loop indefinitely. This might enable a denial-of-service, if the application has not taken appropriate and prudent steps to limit the run-time of SQL statements. This is not a vulnerability, as there are countless perfectly valid SQL queries, especially queries involving recursive common table expressions, that also run essentially forever. (details)
