CVE-2023-6345Chrome — integer overflow in the graphics library

An integer overflow in Skia, the graphics library inside Chrome, lets an attacker who already controls the rendering process break out of it through a malicious file. The same library ships in ChromeOS, Android and Flutter.

YOUR NEXT MOVE

Update Chrome to 119.0.6045.199 or later, then check whatever else is built on the same graphics library — the advisory names ChromeOS, Android and Flutter.
