Google Chrome Zero-Day Bugs Under Exploit

Recently, Google has released another major update for its Chrome browser. This update once again addressed two serious zero-day bugs affecting Chrome components.

Although, Google hasn’t released details about the vulnerabilities yet. The tech giant implements this practice to avoid further exploitation of the bugs until a majority of the users receive the fix. Nonetheless, this practice becomes significantly important when it is about disclosing zero days.

Nonetheless, Google has briefly mentioned the nature of the bugs in its latest advisory announcing Chrome 93.0.4577.82 stable release.

The first of these high-severity zero-days include an out-of-bounds write vulnerability in the V8 component (CVE-2021-30632). Whereas the second bug includes a use after free flaw in Indexed DB API (CVE-2021-30633).

Google has currently not disclosed the name of the researcher that reported the vulnerabilities. Nor has the tech giant announced any bounties yet.

However, they did confirm active exploitation of the two flaws.

Google is aware that exploits for CVE-2021-30632 and CVE-2021-30633 exist in the wild.

Alongside the two Chrome zero-days, Google has also patched 9 other high-severity vulnerabilities.

Some notable bugs include CVE-2021-30625 reported by a researcher from Cisco Talos – a use after free flaw in Selection API, and CVE-2021-30626 – an out-of-bounds memory access in ANGLE that caught Google’s attention following the report from Jeonghoon Shin of Theori. The tech giant has announced a $7500 bounty for each of these bug reports.

Besides, a type confusion vulnerability in Blink layout also won the researcher Aki Helin a bounty of $5000.

The latest Chrome 93.0.4577.82 release is available for all desktop users (Windows, Mac, and Linux). Therefore, users must ensure updating their devices with the latest versions to avoid any threats.

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.
