Google: Google fixes zero-day vulnerability with emergency Chrome update: All details here – Times of India

Google has released an emergency Chrome security update to patch a zero-day vulnerability that was exploited in attacks since the start of the year. The version is currently being rolled out to users in the Stable Desktop channel.
“The Stable and extended stable channel has been updated to 112.0.5615.121 for Windows, Mac and Linux which will roll out over the coming days/weeks,” Google said. The company is keeping the details of the vulnerability under sheets until a majority of users are updated with a fix.
“We will also retain restrictions if the bug exists in a third party library that other projects similarly depend on, but haven’t yet fixed,” the company said.
Users can check for updates by going to the Chrome menu > Help > Google Chrome.

Google is aware of the exploit
Google said in a security advisory that it is aware that an exploit for CVE-2023-2033 exists in the wild. Clement Lecigne of Google’s Threat Analysis Group (TAG), whose major mission is to protect Google customers from state-sponsored attacks, reported the bug.
BleepingComputer reported that the zero-day vulnerability is due to a high-severity type confusion weakness in the Chrome V8 JavaScript engine.

Google makes Chrome faster on macOS
Recently, Google made some optimisations for the macOS version of the Chrome browser that resulted in significant speed improvements. According to a company blog post, the browser’s performance on Apple’s Speedometer browser benchmark has surpassed previous levels and is currently faster than ever.
Google said that the latest version of Chrome underwent significant optimisation efforts to enhance its speed and efficiency. The efforts involved improved parsing for specific CSS and JavaScript functions and more efficient pointer compression.
Google also optimised pointer compression and decompression in both V8 and Oilpan, ensuring not to compress high-traffic fields. The optimisations led to a 10% performance increase on Apple’s Speedometer 2.1 browser benchmark in just three months.
