Google Chrome must be updated without delay, vulnerabilities are exploited

An update for Google Chrome is available and must be installed quickly: it fixes several vulnerabilities, two of which are exploited.

For Internet users who use Google Chrome to go to the web, now is the time to check that the browser is up to date – and if not, upgrade now. In a blog post published on September 13, Google announced the release of software version 93.0.4577.82, for Windows, Mac OS and Linux platforms. It is dedicated to security.

In total, the update closes eleven security breaches, all considered serious. But two of them are more worrying than the other two: indeed, Google reports that malicious uses of the vulnerabilities identified under the codes of CVE-2021-30632 and CVE-2021-30633 have been identified. Under these conditions, it is better not to wait to update Chrome.

Google is pushing an update to its web browser which plugs a few holes in its software.

The first flaw affects V8, the JavaScript engine of Google Chrome, which is used to execute instructions in JavaScript – an open source engine that turns out to be used by other browsers, such as Edge, Opera, Brave or Vivaldi. Google evokes writing off limits. As for the other breach, it concerns a release after use (“use after free” in the IndexedDB API.

Google Chrome, which is the most widely used web browser in the world today, is exposed to vulnerabilities from time to time, just like any software. But it also occasionally faces breaches that are actively used to harm Internet users. Since the beginning of the year alone, a few incidents of this type have been documented, in February, April and June.
