CVE-2014-3559

El backend de almacenaje oVirt en Red Hat Enterprise Virtualization 3.4 no borra instantáneas de la memoria cuando elimina una VM, incluso cuando borrar después de eliminar (wipe-after-delete o WAD) está configurado para el disco de la VM, lo que permite a usuarios remotos autenticados con ciertas credenciales leer porciones de la memoria eliminada de la VM y obtener información sensible a través de un volumen de almacenaje no inicializado.

It was found that the oVirt storage back end did not wipe memory snapshots when VMs were deleted, even if wipe-after-delete (WAD) was enabled for the VM's disks. A remote attacker with credentials to create a new VM could use this flaw to potentially access the contents of memory snapshots in an uninitialized storage volume, possibly leading to the disclosure of sensitive information.

Red Hat Enterprise Virtualization is a feature-rich server virtualization management system that provides advanced capabilities for managing Red Hat virtualization infrastructure for Servers and Desktops. It was found that the oVirt storage back end did not wipe memory snapshots when VMs were deleted, even if wipe-after-delete was enabled for the VM's disks. A remote attacker with credentials to create a new VM could use this flaw to potentially access the contents of memory snapshots in an uninitialized storage volume, possibly leading to the disclosure of sensitive information.
