Here we go again.

Hey Chrome users, guess what? The party never stops. Just when we thought we had dodged a bullet with Google patching a zero-day vulnerability just a few days ago, another one pops up.

Google’s security team recently found themselves in a déjà vu situation, discovering a second zero-day exploit (CVE-2023-2136) just days after patching another one.

The good news is that they’re on it. “Google is aware that an exploit for CVE-2023-2136 exists in the wild,” Google wrote in a release update. Thankfully, a patch is being rolled out now.

What is it this time, Google?

The official report says that this flaw could allow a remote attacker, who’s already compromised the renderer process, to perform a sandbox escape through a crafted HTML page.

In plain English, it means they could run untrusted, malicious code on your computer and potentially spread infection. Yea, not good!

Now, you might be wondering if this is connected to the other zero-day vulnerability Google patched last Friday (CVE-2023-2033). We don’t know for sure, but both flaws seem to exploit specially crafted HTML pages so they could be related.

The good news is that Google’s been working double-time to patch these flaws. The fix for CVE-2023-2136 is already rolling out, arriving as Chrome version 112.0.5615.137.

How to update Google Chrome

So, how do you update? Keep an eye out for that update button in the upper-right corner of your browser, or head to the “About Chrome” tab to automatically receive the update.

If you don’t feel like waiting, you can always manually update using the instructions below:

Navigate to Help, then click About Google Chrome.Screenshot of google chrome showing about google chrome menu item

You’ll see the below page with all the information you need about your current version of Google Chrome. When this page opens, Chrome also checks for pending updates, so you’ll see an animation while it checks and another spirit while it updates your browser if it finds an update.Screenshot of google chrome about page

Google will prompt you to Relaunch your browser if you have an update. It’s essential to do so, as your browser isn’t fully updated until it restarts.Screenshot of google chrome prompt to relaunch

In the meantime, here are some tips to stay secure while browsing online:

  1. Keep your software up-to-date (like, right now with Chrome).
  2. Don’t click on suspicious links or open unknown attachments.
  3. Use strong, unique passwords for each account.
  4. Enable two-factor authentication whenever possible.

Remember, folks, the internet can be a wild place, but with a little vigilance and timely updates, we can keep our browsing experience as secure as possible. Stay safe out there.
