Descriptions

Integer signedness error in the NE2000 emulator in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to trigger a heap-based buffer overflow via certain register values that bypass sanity checks, aka QEMU NE2000 "receive" integer signedness error. NOTE: this identifier was inadvertently used by some sources to cover multiple issues that were labeled "NE2000 network driver and the socket code," but separate identifiers have been created for the individual vulnerabilities since there are sometimes different fixes; see CVE-2007-5729 and CVE-2007-5730.

Un error en la propiedad signedness de enteros en el emulador NE2000 en QEMU versión 0.8.2, tal y como es usado en Xen y posiblemente otros productos, permite a usuarios locales desencadenar un desbordamiento de búfer en la región heap de la memoria por medio de ciertos valores de registro que omiten las comprobaciones de saneamiento, también se conoce como error en la propiedad signedness de enteros "receive" de QEMU NE2000. NOTA: este identificador fue usado inadvertidamente por algunas fuentes para cubrir múltiples problemas que fueron etiquetados como "NE2000 network driver and the socket code”, pero se han creado identificadores separados para las vulnerabilidades individuales ya que existen algunas veces diferentes correcciones; consulte CVE-2007-5729 y CVE-2007-5730.
