Description Sam Fowler 2018-03-21 00:05:03 EDT

SQLite through version 3.22.0 is vulnerable to a NULL pointer dereference when using databases that have been corrupted with 'CREATE TABLE AS' statements. An attacker could exploit this with a crafted database file to trigger a crash and resulting denial of service.
