CVE-2018-1062: Red Hat Ovirt-Engine

Medium severity, CVSS 5.3. EPSS: 1.4% chance of exploitation in the next 30 days.

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.

Affected products

• Red Hat Ovirt-Engine: from 4.1.0, before 4.1.9 (fixed in 4.1.9)
