Title: Cinder LVM volume driver does not support secure deletion
Reporter: Rongze Zhu (UnitedStack)
Products: Cinder
Affects: 2013.1 (Grizzly) and later
Description:
Rongze Zhu from UnitedStack reported a vulnerability in the Cinder
LVM volume driver. The contents of LVM snapshots may not be cleared
upon deletion even when secure deletes are configured, resulting in
potential exposure of latent data to subsequent servers for other
tenants. Only setups using LVMVolumeDriver are affected.
Havana (development branch) fix:

Notes:
This fix is included in the havana-2 development milestone and will
appear in a future 2013.1.3 release.
