Background
Node.js is a powerful platform built on Chrome's JavaScript runtime, designed for building fast and scalable network applications. It employs an event-driven, non-blocking I/O model, making it lightweight and efficient for data-intensive real-time applications across distributed devices. However, recent security findings have revealed vulnerabilities that could compromise the integrity of applications built on this platform.
Vulnerability Detail
The vulnerability identified in Node.js, specifically in the c-ares library, is a use-after-free issue in the read_answers() function (CVE-2025-31498). This flaw can lead to potential memory corruption, which may allow an attacker to execute arbitrary code or crash the application. The vulnerability arises from improper memory management, where the application continues to reference memory that has already been freed, leading to unpredictable behavior and security risks.
How To Fix
