What is CVE-2020-11656?

The vulnerability in the SQLite Database Engine arises from a flaw in the ALTER TABLE implementation, which can lead to a use-after-free condition. This can be triggered by certain ORDER BY clauses within compound SELECT statements, potentially allowing an attacker to exploit the freed memory. Such vulnerabilities can lead to unpredictable application behavior, including data corruption or arbitrary code execution.
