Release Date: 2016-11-15 Last Updated: 2016-11-15 Potential Security Impact: Remote: Denial of Service (DoS) Source: Hewlett Packard Enterprise, 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 Base Metrics ================= Reference, CVSS V3 Score/Vector, CVSS V2 Score/Vector CVE-2016-8611 4.3 CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L 4.0 (AV:N/AC:L/Au:S/C:N/I:N/A:P) Information on CVSS is documented in HPE Customer Notice HPSN-2008-002 here: https://h20564.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-c01345499 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.
