ovirt-engine: When Wipe After Delete (WAD) and Enable Discard are both enabled for a VM disk, discarded data might not be wiped after the disk is removed.

A vulnerability was discovered in oVirt 4.1.x before 4.1.9, where the combination of Enable Discard and Wipe After Delete flags for VM disks managed by oVirt, could cause a disk to be incompletely zeroed when removed from a VM. If the same storage blocks happen to be later allocated to a new disk attached to another VM, potentially sensitive data could be revealed to privileged users of that VM.

ansible: Security issue with lookup return not tainting the jinja2 environment

Ansible before versions 2.3.1.0 and 2.4.0.0 fails to properly mark lookup-plugin results as unsafe. If an attacker could control the results of lookup() calls, they could inject Unicode strings to be parsed by the jinja2 templating system, resulting in code execution. By default, the jinja2 templating language is now marked as 'unsafe' and is not evaluated.
