# SQLite: deep expression nesting in count(*) exhausts the stack, crashing the process

SQLite versions before 3.54.0 contain a stack exhaustion bug in countOfViewOptimization(). A crafted query over a large multi-row VALUES clause, or a database file with a crafted view, can crash the host process, causing denial of service.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Run `sqlite3 --version` or check the bundled SQLite version in your application's dependencies
- Search your dependency lockfiles for SQLite versions below `3.54.0`

## Fix

- SQLite: move to `3.54.0` or later

## From the sources

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.
