After reporting earlier this week on a critical zero-day flaw in Chrome, it turns out that Google's browser is not the only one affected by this bug.

As reported by The Verge, other Chromium-based browsers, including Firefox, Edge, and Brave, are also vulnerable to the potential attack. However, all companies with affected browsers have released new versions to fix this security flaw.

The flaw itself (tracked as CVE-2023-4863) is caused by a weakness in the WebP heap buffer overflow that, if exploited, can be used to execute arbitrary code within Chrome, Firefox, Edge, Brave Chrome, Firefox, Edge, and Brave. To make matters worse, Google revealed in a security advisory that means exist to exploit this vulnerability and that hackers have already used this means in their attacks.

For this reason, users should immediately update their browsers to the latest version in order to avoid becoming a victim of an attack that exploits this vulnerability. The following are the latest versions of Chrome, Firefox, Edge, and Brave (at the time of publication), so you can check if your browser is completely up-to-date:

If you think that updating all of your browsers is too much trouble, you should update all of them, as this vulnerability also affects many popular applications.

Stack is a web browser that is not yet fully up-to-date.

According to Stack Diary, Electron-based apps and cross-platform apps built with Flutter are also vulnerable. The encrypted messaging app Signal and the free image viewer Honeyview are both Electron-based, while GIMP, LibreOffice, Telegram, and many good Android apps are made in Flutter. At the same time, Apple also updated macOS Ventura to version 13.5.2 last week through an emergency security update to address the flaw.

This means that the browser and several other programs on PCs and Macs, as well as many Android apps on the best Android phones, need to be updated. This means a lot of updating to protect against attacks that take advantage of this security flaw.

When it comes to major security flaws like this one, the most important thing you can do to stay safe is to ensure that all software is updated as soon as a security fix becomes available. While this may be annoying, updating all software is much easier than dealing with identity theft and other consequences.

In addition to updating, you should use the best antivirus software on your PC, the best Mac antivirus software on your Apple computer, and the best Android antivirus app on your Android smartphone. Installing the latest software updates and using antivirus software on your devices will ensure that you are protected from any cyber attacks.

All major browsers and popular apps are affected by this critical security flaw, but other software can also be attacked using this flaw. Therefore, we recommend that you install the latest updates for other software as well, just in case.
