Descriptions

Certain MMU virtualization operations in Xen 4.2.x through 4.4.x, when using shadow pagetables, are not preemptible, which allows local HVM guest to cause a denial of service (vcpu consumption) by invoking these operations, which process every page assigned to a guest, a different vulnerability than CVE-2014-5146.

Ciertas operaciones de la virtualización MMU en Xen 4.2.x hasta 4.4.x, cuando se utilizan las tablas de las páginas shadow, no son preferentes, lo que permite a huéspedes locales HVM causar una denegación de servicio (consumo de vcpu) mediante la invocación de estas operaciones, las cuales procesan cada página asignada a un huésped, una vulnerabilidad diferente a CVE-2014-5146.

Multiple vulnerabilities have been found in Xen, the worst of which can allow remote attackers to cause a Denial of Service condition. Versions less than 4.4.2-r1 are affected.
