https://notcve.org/view.php?id=CVE-2012-1003

Multiple integer overflows in Opera 11.60 and earlier allow remote attackers to cause a denial of service (application crash) via a large integer argument to the (1) Int32Array, (2) Float32Array, (3) Float64Array, (4) Uint32Array, (5) Int16Array, or (6) ArrayBuffer function. NOTE: the vendor reportedly characterizes this as "a stability issue, not a security issue." Múltiples desbordamientos de enteros en Opera v11.60 y anteriores permiten a atacantes remotos causar una denegación de servicio (caída de la aplicación) a través de un argumento entero demasiado grande a las funciones (1) Int32Array, (2) Float32Array, (3) Float64Array, (4) Uint32Array, (5 ) Int16Array, o (6) ArrayBuffer. NOTA: El proveedor indica que "se trata de un problema de estabilidad, no un problema de seguridad". • http://blog.vulnhunt.com/index.php/2012/02/02/cal-2012-0004-opera-array-integer-overflow https://exchange.xforce.ibmcloud.com/vulnerabilities/73027 • CWE-189: Numeric Errors •
