Google Chrome zero-day bug

Heads up, Chrome users! Google has just fixed another zero-day bug in its Chrome browser that was under exploitation. Since the fix is out, make sure to update your browsers at the earliest.

Google Chrome Zero-Day Fixed

Reportedly, a serious zero-day vulnerability exists in the Google Chrome browser that may potentially cause trouble to the users.

Regretfully, the vulnerability first caught the attention of criminal hackers before the Microsoft security researcher Alison Huffman. Consequently, the bug went under exploitation in the wild before the vendors could fix it.

However, after discovering this bug, Huffman, from the Microsoft Browser Vulnerability Research, reported the bug to Google.

The vulnerability has received the CVE ID CVE-2021-21166. Whereas, Google has identified it as a high-severity “Object lifecycle issue in audio”.

Google has fixed this vulnerability with the release of Chrome 89.0.4389.72 stable version for Windows, Mac, and Linux. Like always, Google hasn’t disclosed any details about the vulnerability to prevent further damages before the users could fix it.

Nonetheless, they do admit the active exploitation of this flaw in their post.

Google is aware of reports that an exploit for CVE-2021-21166 exists in the wild.

Update Your Browser Now

Aside from the zero-day, the latest Chrome browser release also includes 46 other security fixes. These include 8 high-severity vulnerabilities, 6 medium-severity flaws, and 8 low-severity bugs.

These vulnerabilities caught the attention of different researchers who then reported them to Google.

The high-severity bugs include 2 other bugs also reported by Alison Huffman (CVE-2021-21163 and CVE-2021-21165).

Since this browser update includes so many security fixes, all Chrome users must ensure updating their devices at the earliest.

This recent fix marks the second consecutive Chrome zero-day fix from Google in consecutive months. Earlier, they patched another zero-day vulnerability in February that Google described as a heap buffer overflow in V8.

Whereas, before that, it patched numerous zero-days in Chrome in 2020 as well.

Analytics

The _ga is asssociated with Google Universal Analytics - which is a significant update to Google's more commonly used analytics service. This cookie is used to distinguish unique users by assigning a randomly generated number as a client identifier. It is included in each page request in a site and used to calculate visitor, session and campaign data for the sites analytics reports. By default it is set to expire after 2 years, although this is customisable by website owners.

The _gat global object is used to create and retrieve tracker objects, from which all other methods are invoked. Therefore the methods in this list should be run only off a tracker object created using the _gat global variable. All other methods should be called using the _gaq global object for asynchronous tracking.

_gid works as a user navigates between web pages, they can use the gtag.js tagging library to record information about the page the user has seen (for example, the page's URL) in Google Analytics. The gtag.js tagging library uses HTTP Cookies to "remember" the user's previous interactions with the web pages.
