Background
The node-sqlite3 package is a popular Node.js library that provides a simple interface for interacting with SQLite databases. It is widely used for its efficiency and ease of integration in various applications. However, prior to version 5.0.3, the package is susceptible to a Denial of Service (DoS) vulnerability that can disrupt the normal operation of applications relying on it.
Vulnerability Detail
The vulnerability arises from the improper handling of the toString function when an invalid Function object is passed as a parameter. This can lead to a crash of the V8 engine, which is the JavaScript engine used by Node.js, resulting in a Denial of Service condition. Attackers can exploit this vulnerability by sending crafted inputs that trigger the crash, thereby affecting the availability of the application.
