RESOLUTION
HPE has provided the following updates to resolve this vulnerability in the
impacted versions of Helion OpenStack (HOS) and CloudSystem:
* For HOS v3.x, please install HOS v3.0.3
* For HOS v4.x, please install HOS v4.0.1
HOS updates can be downloaded using the following link:
<http://www.hpe.com/software/entitlements>
* For CloudSystem, please install CloudSystem v10.0.1:
CloudSystem update can be downloaded using the following link:
<https://h20392.www2.hpe.com/portal/swdepot/displayProductInfo.do?productNumb
r=Z7550-63210>
**Note:** Security controls built into the Helion OpenStack (HOS) and
CloudSystem reduce the risk posed by this vulnerability to low. Since HOS and
CloudSystem tenants have access only to virtual machines and not the KVM
compute host servers, an attacker would first need to gain access to the KVM
compute host server in order to exploit this vulnerability.
