Description Kurt Seifried 2012-11-01 18:35:21 UTC
Thierry Carrez (thierry@openstack.org) has released information reported by Gabe Westmaas (Rackspace):

Title: Authentication bypass for image deletion
Reporter: Gabe Westmaas (Rackspace)
Products: Glance
Affects: Essex, Folsom, Grizzly

Description:
Gabe Westmaas from Rackspace reported a vulnerability in Glance
authentication of image deletion requests. Authenticated users may be
able to delete arbitrary, non-protected images from Glance servers. Only
Folsom/Grizzly deployments that expose the v1 API are affected by this
vulnerability. Additionally, Essex deployments that use the
delayed_delete option are also affected.

There have been some important updates that have occurred since the
publication of this advisory:

1) When the advisory was published, the patch for the stable/essex
branch had not been merged.  It has now been merged and is *different*
than the original patch.  If you pulled the earlier patch, please update
to the final version.

https://github.com/openstack/glance/commit/efd7e75b1f419a52c7103c7840e24af8e5deb29d

2) It was discovered that the patches submitted for stable/folsom and
master (grizzly) did not completely solve the problem.  The original
patch only fixed the problem for the v1 API.  The problem still existed
for the v2 API.  Please see this commit for the additional patch:
