This week, both Google and Mozilla rolled out critical security updates for Chrome and Firefox, addressing a combined 17 vulnerabilities, including several high-severity issues.

Chrome’s update, now available for Windows, macOS, and Linux users (versions 129.0.6668.89/.90), tackles four security flaws, three of which were flagged by external researchers. These high-severity bugs include an integer overflow in Layout, insufficient data validation in Mojo, and a vulnerability in V8. Google rewarded a $10,000 bounty for the integer overflow discovery and is still evaluating the rewards for the others. Fortunately, there’s no indication that any of these flaws have been exploited in the wild.

Mozilla also announced the release of Firefox 131, patching 13 vulnerabilities, including seven high-severity flaws. Some of these bugs specifically impact Android users, preventing them from exiting full-screen mode or potentially granting cross-origin access to PDF and JSON contents. Firefox 131 also fixes memory safety bugs that could lead to code execution, though none of these flaws appear to have been exploited.

In addition to Firefox, Mozilla has updated Firefox ESR and Thunderbird, urging users to apply these security patches promptly to ensure their systems remain protected.

By applying these patches, you not only protect your personal data but also help secure the broader online ecosystem. Don’t wait—take action now to stay safe and keep your digital experience running smoothly.
