Potential Security Impact: Remote Access Restriction Bypass, Unauthorized

Source: Hewlett Packard Enterprise, Product Security Response Team

Potential vulnerabilities have been identified in HPE Helion OpenStack
Glance. The vulnerabilities can be remotely exploited to allow access
restriction bypass and unauthorized access.

A malicious tenant is able to reuse deleted Glance image IDs to share
malicious images with other tenants in a manner that is undetectable to the
victim tenant if the Helion OpenStack administrators have both:

  1. Edited the policy.json file to allow non-admin tenants to share images
with other tenants or edited policy.json to allow non-admin tenants to create
public images.
  2. Deleted image IDs from the Glance database, either manually or using the
purge tool ("glance-manage db purge").

    Further details are available in OSSN-0075 here:


  - CVE-2016-4383
  - OSSN-0075
  - PSRT110227, PSRT110231

HPE has provided the following mitigation instructions for HPE Helion
OpenStack Glance:

 * This procedure ensures that images shared between two tenants who trust
each other are not maliciously replaced by a malicious tenant reusing a
deleted image ID. Perform the following action:

  1. The admin should update the policy.json file so that only admins can
deactivate/reactivate images:
    "deactivate": "role:admin",
    "reactivate": "role:admin",
  2. All public or shared images should be quarantined by marking them as
deactivated using the Glance API.
  3. The admin should inspect all public/shared images to see if they have
been replaced by malicious images.
  4. Any images which cannot be confirmed to be non-malicious should be left
  5. Images which can be confirmed to be non-malicious images can be
reactivated using the Glance API.

    * **Note:** Images can be confirmed to be non-malicious for example by
examining the Glance logs or backup Glance databases to show that the image
ID has not been recycled.
