Descriptions

OpenStack Compute (Nova) Folsom, Grizzly, and Havana, when use_cow_images is set to False, does not verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) by transferring an image with a large virtual size that does not contain a large amount of data from Glance. NOTE: this issue is due to an incomplete fix for CVE-2013-2096.

OpenStack Compute (Nova) Folsom, Grizzly, y Habana, cuando use_cow_images se establece como False, no verifica el tamaño virtual de una imagen qcow2, que permite a usuarios locales provocar una denegación de servicio (consumo de disco del sistema de archivos host) mediante la transferencia de una imagen con un tamaño virtual grande que no contiene una gran cantidad de datos desde Glance. NOTA: este problema se debe a una corrección incompleta de CVE-2013-2096.

Darragh O'Reilly discovered that OpenStack Nova did not properly set up its sudo configuration.
