Earlier this week, it was reported that a vulnerability in Facebook’s popular WhatsApp messaging service made it possible for attackers to spread spyware to smartphones via phone calls made through the app.
To do so, hackers exploited a bug within WhatsApp known as a buffer-overflow vulnerability, which the company said it quickly fixed, the Financial Times first reported. A buffer overflow is exactly what its name implies; it’s an issue that can occur when an app is flooded with more data than it can store in its buffer, or temporary storage space.
