OSSA-2015-003: Glance user storage quota bypass

Date

January 26, 2015

CVE

CVE-2014-9623

Affects

  • Glance: up to 2014.1.3 and 2014.2 versions 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.

Notes

  • This fix will be included in the kilo-2 development milestone and in future 2014.2.2 (juno) and 2014.1.4 (icehouse) releases.
