CVE-2015-6773

Estado: ModificadaAlta (7.5)—

La implementación de la convolución en Skia, como se utiliza en Google Chrome en versiones anteriores a 47.0.2526.73, no restringe adecuadamente longitudes de fila, lo que permite a atacantes remotos causar una denegación de servicio (acceso a memoria fuera de rango) o posiblemente tener otro impacto no especificado a través de datos de gráficas manipuladas.
