Description Petr Matousek 2010-06-16 12:43:15 EDT
A flaw was found in the way the Virtual Desktop Server Manager (VDSM) handled the removal of a virtual machine's (VM) data back end (such as an image or a volume). When removing an image or a volume, it was not securely deleted from its corresponding data domain as expected. A guest user in a new, raw VM, created in a data domain that has had VMs deleted from it, could use this flaw to read limited data from those deleted VMs, potentially disclosing sensitive information.
