CVE-2020-24736Public exploit

Application crash via stale window-function references

Published Apr 11, 2023 · Updated Feb 11, 2025

Buffer overflow in SQLite3 3.27.1 and earlier allows local users to crash applications by executing crafted window-function SQL. The ORDER BY resolver converts a window-function expression to a result-column alias but leaves its Window objects linked in Select.pWin. Exploitation requires the ability to execute crafted SQL locally, and the reported consequence is limited to crashing the hosting process.
