SQLite before 3.54.0 contains a stack exhaustion vulnerability in countOfViewOptimization() that allows attackers to crash the host process via count(*) over a large multi-row VALUES clause. Attackers supplying SQL or a database file with a crafted view can trigger deeply nested TK_PLUS expressions whose recursive freeing in sqlite3ExprDeleteNN() exhausts the C stack, causing denial of service.

Description from the National Vulnerability Database, published by VulnCheck

What it means for a small business

If your business uses SQLite, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
