Title: Live migration can leak root disk into ephemeral storage
Reporter: Loganathan Parthipan (HP)
Products: Nova
Affects: All supported versions

Loganathan Parthipan from Hewlett Packard reported a vulnerability in the Nova libvirt driver. By spawning a server with the same flavor as another user's migrated virtual machine, an authenticated user can potentially access that user's snapshot content resulting in information leakage. Only setups using KVM live block migration are affected.
