The host is installed with Google Chrome before 53.0.2785.113 and is prone to a denial of service vulnerability. A flaw is present in the application, which fails to ensure that the recipient of a certain IPC message is a valid RenderFrame or RenderWidget. Successful exploitation allows attackers to cause denial of service (invalid pointer dereference and application crash) or possibly have unspecified other impact by leveraging access to a renderer process.
