"value": "An issue was discovered in the default FilterScheduler in OpenStack Nova 16.0.3. By repeatedly rebuilding an instance with new images, an authenticated user may consume untracked resources on a hypervisor host leading to a denial of service, aka doubled resource allocations. This regression was introduced with the fix for OSSA-2017-005 (CVE-2017-16239); however, only Nova stable/pike or later deployments with that fix applied and relying on the default FilterScheduler are affected."

Mediante la reconstrucci\u00f3n repetida de una instancia con nuevas im\u00e1genes, un usuario autenticado podr\u00eda consumir recursos no seguidos en un host de hipervisor, lo que conduce a una denegaci\u00f3n de servicio (DoS). Esto tambi\u00e9n se conoce como dobles asignaciones de recursos. Esta regresi\u00f3n fue introducida con el fix para OSSA-2017-005 (CVE-2017-16239); sin embargo, solo las implementaciones Nova stable/pike o siguientes con dicho fix aplicado y dependientes del FilterScheduler se han visto afectadas."
