Google has issued a warning about two security flaws in the latest stable version (81) of its popular web browser Chrome. According to Forbes, Google is keeping the details secret to prevent hackers from exploiting them, but the company also says it has not recorded any hacks using this method.

What to do: Make sure your Chrome browser is up to date. The latest version with the patch is 81.0. 4044. 129 on Windows and Mac, which Google is pushing out to all Chrome users now, so you may already have it. You can check your version in the Chrome menu, then restart.

The details: While the specific method of exploiting the flaw is being kept secret, users will see one of two error messages: “STATUS_ACCESS_VIOLATION” or “STATUS_INVALID_IMAGE_HASH.” If you see these errors, you should upgrade immediately. Forbes reports that the vulnerability could allow hackers to take control of your system.

Bottom Line: While Google has been quick to patch these flaws, it is still important to make sure you are not affected. Check your own Chrome version immediately to avoid issues with these vulnerabilities.
