The host is installed with Google Chrome before 34.0.1847.131 or Apple Safari before 6.1.4 or 7.x before 7.0.4 and is prone to denial of service vulnerability. A flaw is present in the application, which fails to properly check renderer state upon a focus event. Successful exploitation allows attackers to cause a denial of service or possibly have unspecified other impact via vectors that leverage "type confusion" for SELECT elements.
