> Eric Windisch from Cloudscaling reported a vulnerability in libvirt LVM-backed instances. The physical volume content was not wiped out before being reallocated and passed to an instance, which may result in the disclosure of information from previously-allocated logical volumes. Only setups using libvirt and LVM-backed instances (libvirt_images_type=lvm) are affected.
