OSSA-2014-028: Glance store DoS through disk space exhaustion

Date:August 21, 2014
CVE:CVE-2014-5356

Affects

  • Glance: up to 2013.2.3 and 2014.1 versions up to 2014.1.2

Description

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).
