CVE-2017-9310

QEMU (también conocido como Quick Emulator), cuando se integra con soporte de emulación e1000e NIC, permite que usuarios privilegiados invitados locales del sistema operativo provoquen una denegación de servicio (bucle infinito) mediante vectores relacionados con la colocación de la cabecera receive/transmit del descriptor TDH/RDH???? fuera del búfer del descriptor asignado.

KVM is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines that use KVM in environments managed by Red Hat products. The following packages have been upgraded to a later upstream version: qemu-kvm-rhev. Security Fix: A stack buffer overflow flaw was found in the Quick Emulator built with the Network Block Device client support. The flaw could occur while processing server's response to a 'NBD_OPT_LIST' request. A malicious NBD server could use this issue to crash a remote NBD client resulting in DoS or potentially execute arbitrary code on client host with privileges of the QEMU process.
