Descriptions

Integer overflow in libvirt before 0.9.3 allows remote authenticated users to cause a denial of service (libvirtd crash) and possibly execute arbitrary code via a crafted VirDomainGetVcpus RPC call that triggers memory corruption.

Desbordamiento de entero en libvirt anterior a v0.9.3 permite a usuarios autenticados remotamente provocar una denegación de servicio (caída libvirtd) y posiblemente ejecutar código arbitrario a través de una llamada manipulada VirDomainGetVcpus RPC que provoca corrupción de memoria.
