Description

Red Hat Enterprise Virtualization is a feature-rich server virtualization
management system that provides advanced capabilities for managing Red Hat
virtualization infrastructure for Servers and Desktops.

It was found that the oVirt storage back end did not wipe memory snapshots
when VMs were deleted, even if wipe-after-delete (WAD) was enabled for the
VM's disks. A remote attacker with credentials to create a new VM could use
this flaw to potentially access the contents of memory snapshots in an
uninitialized storage volume, possibly leading to the disclosure of
sensitive information. (CVE-2014-3559)

This issue was discovered by Idan Shaby and Allon Mureinik of Red Hat.

All rhevm users are advised to upgrade to these updated packages, which
correct this issue.
