Details

USN-6073-1 fixed a vulnerability in Cinder. Unfortunately the update
introduced a regression with detaching volumes. The security fix has been
removed pending further investigation.

We apologize for the inconvenience.

Original advisory details:

Jan Wasilewski and Gorka Eguileor discovered that Cinder incorrectly
handled deleted volume attachments. An authenticated user or attacker could
possibly use this issue to gain access to sensitive information.

This update may require configuration changes to be completely effective,
please see the upstream advisory for more information:
