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 -
