CVE-2007-5730

Estado: ModificadaAlta (7.2)—

Un desbordamiento de búfer en la región heap de la memoria en QEMU versión 0.8.2, como es usado en Xen y posiblemente otros productos, permite a usuarios locales ejecutar código arbitrario por medio de datos diseñados en la opción "net socket listen", también se conoce como desbordamiento de pila "net socket" de QEMU. NOTA: algunas fuentes han usado el CVE-2007-1321 para referirse a este problema como parte de "NE2000 network driver and the socket code”, pero este es el identificador correcto para la vulnerabilidad de escucha de socket de red individual.
