CVE-2014-5263

Estado: ModificadaMedia (6.8)—

vmstate_xhci_event en hw/usb/hcd-xhci.c en QEMU 1.6.0 no termina la lista con la macro VMSTATE_END_OF_LIST, lo que permite a atacantes causar una denegación de servicio (acceso fuera de rango, bucle infinito, y corrupción de memoria) y posiblemente ganar privilegios a través de vectores no especificados.

CVSS
