Descriptions

Xen 3.4 through 4.2, and possibly earlier versions, does not properly synchronize the p2m and m2p tables when the set_p2m_entry function fails, which allows local HVM guest OS administrators to cause a denial of service (memory consumption and assertion failure), aka "Memory mapping failure DoS vulnerability."

Xen v3.4 hasta v4.2 y posiblemente versiones anteriores, no sincroniza correctamente las tablas p2m y m2p cuando la función set_p2m_entry falla, lo que permite a los administradores de sistemas operativos clientes en HVM locales, causar una denegación de servicio (consumo de memoria y error de aserción), también conocido como "vulnerabilidad de denegación de servicio por fallo en mapeo de memoria.
