Nine fixes at once will surely change your browsing experience.

Google has introduced a new version of the Chrome 129 browser for Windows, Mac and Linux. The update will be available to users gradually over the coming days. Version 129.0.6668.58 for Linux and 129.0.6668.58/.59 for Windows and Mac includes fixes and improvements that will make the browser more stable and secure.

Among the key changes is the fixing of a number of vulnerabilities. In total, nine security issues have been fixed in this version. Among them are vulnerabilities discovered by third-party researchers. One of the most dangerous is the Type Confusion bug in the V8 engine (CVE-2024-8904), which was reported by a researcher under the pseudonym "Popax21". For its discovery, he received a reward of $8000.

Other medium and low severity vulnerabilities were also identified and fixed, including in the download security interface, autofill system, and Omnibox data verification. Developers pay rewards for helping to improve the browser's security. For example, researchers from ChaMd5-H1 received $8,000 for identifying a bug in the V8 implementation, and a number of other specialists received rewards from $1,000 to $2,000 for the vulnerabilities discovered.

Google continues to actively cooperate with researchers around the world to ensure that vulnerabilities do not make it to stable versions of the Chrome browser. Internal checks help with this, as well as analysis tools such as AddressSanitizer and MemorySanitizer.

In addition to external research, the company is also pursuing a number of internal initiatives to ensure maximum security for the branded browser. These measures help to identify and eliminate potential threats at the development stage.
