By uploading a large enough image to a Glance store, an authenticated user may fill the store space because the image_size_cap configuration option is not honored. This may prevent further image upload and/or cause service disruption. Note that the import method is not affected. All Glance setups using API v2 are affected (unless you use a policy to restrict/disable image upload). Juno (development branch) fix: https://review.openstack.org/91764 Icehouse fix: https://review.openstack.org/115280 Havana fix: https://review.openstack.org/115289 Notes: This fix will be included in the Juno-3 development milestone and in future 2013.2.4 and 2014.1.3 releases.
