Description Adam Mariš 2017-06-29 08:33:06 EDT
The glance-manage db in openstack-glance allows deleted image IDs to be reassigned, which allows remote authenticated users to cause other users to boot into a modified image without notification of the change.

The OSSN is here (with mitigation): https://wiki.openstack.org/wiki/OSSN/OSSN-0075
Comment 6 Summer Long 2017-09-05 21:08:47 EDT

For this flaw to be exploited, both non-admin image upload must be permitted and records of deleted IDs must have been purged from the openstack-glance 'images' database table. 
To prevent flaw exploitation:
* Do not allow non-admin users to upload images, or
* If you do permit normal users to upload images, do not purge the 'images' table. Note: It is safe to delete rows from `image_properties`, `image_tags`, `image_members`, and `image_locations` tables.
