3. Description:

OpenStack Image service (glance) 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.

It was discovered that the image_size_cap configuration option in glance was not honored. An authenticated user could use this flaw to upload an image to glance and consume all available storage space, resulting in a denial of service. (CVE-2014-5356)

This update also fixes the following bugs:

* Uploading an image to glance that exceeded the user's current quota setting was rejected, but no message was added to the glance API log to indicate this. This update fixes this bug, and such events are now logged as INFO messages in the glance API log. (BZ#1055550)

* Whenever the 'x-image-meta-store' header was passed to glance-api, the service would check whether the value was a valid store instead of a valid scheme. However, the rest of the store library uses the scheme to identify the store that should be used; this prevented the use of this feature. Glance now verifies that the value of 'x-image-meta-store' is a valid scheme instead of a valid store name. (BZ#1130622)

All openstack-glance users are advised to upgrade to these updated packages, which correct these issues.
