Considering the former report does not apply to normal user (see comment #9), the severity is lower than expected: The quota is overran only until the upload is completed and images are cleaned after.
I also did not consider malicious administrator.
Here is impact description draft #1
Title: Glance user storage quota bypass
Reporter: Tushar Patil (NTT)
Products: Glance
Versions: up to 2014.1.3 and 2014.2 version up to 2014.2.1
Description:
Tushar Patil from NTT reported a vulnerability in Glance. By deleting images that are being uploaded, a malicious user can overcome the storage quota and thus may overrun the backend. Images in deleted state are not taken into account by quota and won't be effectively deleted until the upload is completed. Only Glance setups configured with user_storage_quota are affected.
