‘Google releases emergency fix for zero-day Chrome vulnerability’

The company recommends that all users update their desktop versions of the browser immediately.

Google released an emergency update for Chrome to address a zero-day security flaw.

A vulnerability, known as CVE-2023-2033, “can be exploited by a malicious webpage to run arbitrary code in the browser”. In other words, a user who visits a bad website with a vulnerable browser could have their device “hijacked”. Exploit code for this hole is said to be circulating, the report warns, and so there is already a potential threat from malefactors.

The bug, which occurs in the V8 JavaScript engine, is present in Chrome for desktop versions prior to 112.0.5615.121. That’s the version Google released on April 14 for Windows, Mac, and Linux to fix the security flaw.

This latest version of Chrome also includes “various fixes from internal audits, fuzzing and other initiatives”, according to Google.

“Many of our security bugs are detected using AddressSanitizer, MemorySanitizer, UndefinedBehaviorSanitizer, Control Flow Integrity, libFuzzer, or AFL”, the company added.
