A flaw was found in Skia, a 2D graphics library used in chromium-browser. This improper state validation vulnerability allows a remote attacker, who has already compromised the renderer process, to read memory outside of the security sandbox. This can be achieved by enticing a user to open a specially crafted HTML page, leading to information disclosure.
