Google fixes Chrome zero day exploited in the wild (CVE-2023-6345)

Google has released an urgent security update to fix a number of vulnerabilities in Chrome browser, including a zero-day vulnerability that is being actively exploited in the wild.

CVE-2023-6345, reported by Benoît Sevens and Clément Lecigne of Google’s Threat Analysis Group, is due to an integer overflow in Skia – an open source 2D graphics library commonly used as a graphics engine for Google Chrome, ChromeOS, Android, Flutter, and others.

The company says that the vulnerability is being exploited by attackers, but will not be sharing further details until most users have applied the update.

The company has addressed the vulnerabilities in the Stable channel and users are advised to update to versions 119.0.6045.199 for Mac and Linux and 119.0.6045.199/.200 for Windows, which will roll out over the coming days/weeks.

Google has recently had to fix several zero days in its Chrome browser that have been actively exploited in the wild.

In late September, Google fixed another heap buffer overflow vulnerability, this time in vp8 encoding in libvpx – a Google and AOMedia video codec library.
