Document Subtype: Security Bulletin Document ID: c05333384 Last Updated: 2017-02-24 Release Date: 2017-01-11 Document Version: 1 Potential Security Impact: Remote: Denial of Service (DoS) Source: Hewlett Packard Enterprise, HPE Product Security Response Team VULNERABILITY SUMMARY A potential security vulnerability has been identified with HPE Helion OpenStack Glance image service. This vulnerability could be exploited remotely to allow a Denial of Service (DoS). References: CVE-2016-8611 - OpenStack Glance image service, Remote Denial of Service (DoS) SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed. HP Helion OpenStack all HPE Helion OpenStack all BACKGROUND CVSS Version 3.0 and Version 2.0 Base Metrics Reference V3 Vector V3 Base Score V2 Vector V2 Base Score CVE-2016-8611 CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L 4.3 (AV:N/AC:L/Au:S/C:N/I:N/A:P) 4.0 Information on CVSS is documented in HPE Customer Notice: HPSN-2008-002 RESOLUTION HPE has provided the following mitigations to resolve this issue: Deploy rate-limiting proxies or web application firewalls For all versions of Glance which expose either the v1 or the v2 /images API, operators are recommended to deploy external rate-limiting proxies or web application firewalls. This will provide a front-end layer of protection to Glance. The Glance database should be monitored for abnormal growth. Although rate-limiting does not eliminate this vulnerability, it will slow it to the point where operators can react prior to a Denial of Service occurring. Restrict image creation to the admin role Another possible mitigation is to restrict image creation to the admin role. This should only be done when there are Glance nodes dedicated to end-user access only. For further recommendations on external rate limiting and restricting image creation, please refer to the Open Stack Security Notice OSSN-0076 - https://wiki.openstack.org/wiki/OSSN/OSSN-0076 HISTORY Version:1 (rev.1) - 15 November 2016 Initial release Third Party Security Patches: Third party security patches that are to be installed on systems running Hewlett Packard Enterprise (HPE) software products should be applied in accordance with the customer's patch management policy.
