SQLite report about CVE-2021-36690

This bug is not in the SQLite core library, but rather in an experimental extension that is used to implement the .expert command in the CLI. The code that contains the bug does not appear in standard SQLite builds, though it is included in the sqlite3.exe command-line tool. Applications must link against the extra source code files that implement the extension and take other deliberate actions to activate the extension before the troublesome code can be run. For the rare application that uses the troublesome extension, the consequence of this bug is that malicious SQL can cause a NULL pointer deference and denial of service. (details)
