CVE-2014-8333

El controlador VMware en OpenStack Compute (Nova) anterior a 2014.1.4 permite a usuarios remotos autenticados causar una denegación de servicio (consumo de disco) mediante la eliminación de un instancia en el estado resize.

A flaw was found in the OpenStack Compute (nova) VMWare driver, which could allow an authenticated user to delete an instance while it was in the resize state, causing the instance to remain on the back end. A malicious user could use this flaw to cause a denial of service by exhausting all available resources on the system.

OpenStack Compute launches and schedules large networks of virtual machines, creating a redundant and scalable cloud computing platform. Compute provides the software, control panels, and APIs required to orchestrate a cloud, including running virtual machine instances and controlling access through users and projects. It was discovered that the OpenStack Compute console websocket did not correctly verify the origin header. An attacker could use this flaw to conduct a cross-site websocket hijack attack. Note that only Compute setups with VNC or SPICE enabled were affected by this flaw.
