Description Murray McAllister 2014-08-20 04:13:40 UTC 
The OpenStack project reports:

""
Thomas Leaman and Stuart McLaren from Hewlett Packard reported a
vulnerability in Glance. By uploading a large enough image to a Glance
store, an authenticated user may fill the store space because the
image_size_cap configuration option is not honored. This may prevent
further image upload and/or cause service disruption. Note that the
import method is not affected. All Glance setups using API v2 are
affected (unless you use a policy to restrict/disable image upload).
""

This affects versions up to 2013.2.3 and 2014.1 to 2014.1.2.
