OpenStack Image Service provides discovery, registration, and delivery services for disk and server images. It provides the ability to copy or snapshot a server image and immediately store it away. Stored images can be used as a template to get new servers up and running quickly and more consistently than installing a server operating system and individually configuring additional services. A flaw was found in the OpenStack Image Service import task action. When processing a malicious qcow2 header, glance could be tricked into reading an arbitrary file from the glance host.
