Adobe Acrobat Reader has a serious vulnerability that could allow hackers to take control of your computer. The flaw is a buffer overflow issue present in versions 22.003.20282 and earlier of Acrobat Reader for Windows and Mac.

A buffer overflow occurs when a program writes more data to a buffer than it can hold. This corrupts the memory and allows attackers to inject and run malicious code. In this case, by tricking a user into opening a specially crafted PDF file.

If successfully exploited, a hacker could install programs, view, change or delete data, or create new accounts with full user rights on the affected system. Essentially giving them complete control of your computer while bypassing security protections.

The good news is that Adobe has released updates to fix the problem. It’s important that all Acrobat Reader users update their software immediately to versions 22.003.20283 or later to protect against this critical vulnerability. You can check for updates by opening the Adobe Reader app and selecting “Help > Check for Updates”.

Staying on top of software updates is one of the best ways to avoid falling victim to cyber attacks. So be sure to update Acrobat Reader and any other programs you have that notify you of security patches. Taking quick action now helps keep your data and devices safe from exploitation.
