Chrome Browser Gets Major Security Update


Google this week released a security-themed Chrome browser makeover with patches 28 documented vulnerabilities, some serious enough to lead to code execution attacks.

The new browser refresh is now rolling out to Windows, Mac and Linux users as Chrome 100.0.4896.60. 

Nine of the security defects identified by external researchers are rated high-severity. Use-after-free was the most common type of vulnerability among the issues reported externally, followed by inappropriate implementation.

Google said it paid out $52,000 in bug bounty rewards to the reporting researchers, but the final amount could be much higher, as the company has yet to determine the rewards to be handed out for half of the externally reported vulnerabilities.

The highest bug bounty reward was handed out to Wei Yuan of MoyunSec VLab for a medium severity use-after-free flaw in Shopping Cart.

Chrome 100 arrives less than a week after Google issued an emergency fix to address a zero-day vulnerability in the V8 JavaScript engine. There have been only two documented zero-days in Chrome this year.
