An integer overflow that lead to a heap buffer-overflow in Skia in Google Chrome prior to 66.0.3359.117 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
