Descriptions

Xen 4.5.x through 4.7.x on AMD systems without the NRip feature, when emulating instructions that generate software interrupts, allows local HVM guest OS users to cause a denial of service (guest crash) by leveraging an incorrect choice for software interrupt delivery.

Xen 4.5.x hasta la versión 4.7.x en sistemas AMD sin la funcionalidad NRip, cuando se emulan instrucciones que generan interrupciones de software, permite a usuarios locales de SO huésped HVM provocar una denegación de servicio (caída del invitado) aprovechando una elección incorrecta para la entrega de interrupciones de software.

Multiple vulnerabilities have been found in Xen, the worst of which could lead to the execution of arbitrary code on the host system. Versions less than 4.7.1-r4 are affected.
