Descriptions

OpenStack Compute (Nova) Folsom before 2012.2.2 and Grizzly, when using libvirt and LVM backed instances, does not properly clear physical volume (PV) content when reallocating for instances, which allows attackers to obtain sensitive information by reading the memory of the previous logical volume (LV).

OpenStack Compute (Nova) Folsom antes de 2012.2.2 y Grizzly, cuando utiliza instancias con respaldo libvirt y LVM, no limpia adecuadamente el contenido del volumen físico (PV) cuando se reasignan las instancias, lo que permite a los atacantes obtener información sensible mediante la lectura de la memoria de la anterior volumen lógico (LV).
