Descriptions

An issue was discovered in Xen through 4.9.x allowing x86 SVM PV guest OS users to cause a denial of service (hypervisor crash) or gain privileges because IDT settings are mishandled during CPU hotplugging.

Se ha descubierto un problema en Xen hasta las versiones 4.9.x que permite que usuarios invitados del sistema operativo x86 SVM PV provoquen una denegación de servicio (cierre inesperado del hipervisor) o que puedan obtener privilegios debido a que se gestionó de manera incorrecta la configuración IDT durante la conexión directa a la CPU.

Multiple vulnerabilities have been discovered in the Xen hypervisor, which could result in denial of service, information leaks, privilege escalation or the execution of arbitrary code.
