Descriptions

Xen 4.3.x writes hypervisor mappings to certain shadow pagetables when live migration is performed on hosts with more than 5TB of RAM, which allows local 64-bit PV guests to read or write to invalid memory and cause a denial of service (crash).

Xen 4.3.x escribe asignaciones de hypervisor a ciertas "shadow pagetables" cuando la migración en vivo se realiza en máquinas con más de 5 TB de RAM, lo que permite a usuarios locales de 64-bit PV leer o escribir en memoria no válida y provocar una denegación de servicio (caída).

Multiple vulnerabilities have been found in Xen, the worst of which could lead to arbitrary code execution. Versions less than 4.3.2-r4 are affected.
