Google fixes first actively exploited Chrome zero-day of 2024

January 16, 2024 at 02:14PM

Google has released security updates to address the first Chrome zero-day vulnerability (CVE-2024-0519) exploited since the beginning of the year. This high-severity flaw in the Chrome V8 JavaScript engine allows attackers to access sensitive data, trigger crashes, and potentially execute arbitrary code. Google also fixed two other vulnerabilities (CVE-2024-0517 and CVE-2024-0518), stressing the importance of timely updates.

Key takeaways from the meeting notes on Google’s recent security updates include:

1. Google has released security updates to fix the first Chrome zero-day vulnerability exploited in the wild since the start of the year.
2. The exploit for CVE-2024-0519 was fixed for users in the Stable Desktop channel, with patched versions rolling out worldwide to Windows (120.0.6099.224/225), Mac (120.0.6099.234), and Linux (120.0.6099.224) users less than a week after being reported.
3. The security update may take days or weeks to reach all impacted users, but was available immediately when checked for updates.
4. Users who don’t manually update can rely on Chrome to automatically check for updates and install them after the next launch.
5. The high-severity zero-day vulnerability (CVE-2024-0519) is due to a high-severity out-of-bounds memory access weakness in the Chrome V8 JavaScript engine.
6. CVE-2024-0519 could also be exploited to bypass protection mechanisms such as ASLR to make it easier to achieve code execution via another weakness.
7. Today, Google also patched V8 out-of-bounds write (CVE-2024-0517) and type confusion (CVE-2024-0518) flaws, allowing for arbitrary code execution on compromised devices.
8. Last year, Google fixed eight Chrome zero-day bugs exploited in attacks, some of which were used to deploy spyware on vulnerable devices.

These points summarize the essential details and implications of the security updates discussed in the meeting notes.
