OpenStack Image service (glance) provides discovery, registration, anddelivery services for disk and server images. It provides the ability tocopy or snapshot a server image, and immediately store it away.Stored images can be used as a template to get new servers up and runningquickly and more consistently than installing a server operating system andindividually configuring additional services.It was found that Sheepdog, a distributed object storage system, did notproperly validate Sheepdog image URIs. A remote attacker able to insert ormodify glance image metadata could use this flaw to execute arbitrarycommands with the privileges of the user running the glance service.Note that only OpenStack Image setups using the Sheepdog back end wereaffected.
