Descriptions
The intel_hda_xfer function in hw/audio/intel-hda.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) via an entry with the same value for buffer length and pointer position.
La función intel_hda_xfer en hw/audio/intel-hda.c en QEMU (también conocido como Quick Emulator) permite a administradores locales del SO invitado provocar una denegación de servicio (bucle infinito y consumo de CPU) a través de una entrada con el mismo valor para la longitud del búfer y posición del puntero.
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.
