  Glance allows users to download and delete any file in glance-api
  server

  Fix Released
Status in Glance icehouse series:

Status in Glance juno series:

Status in OpenStack Security Advisories:

Bug description:
  Updating image-location by update images API users can download any file for which glance-api has read permission. 
  And the file for which glance-api has write permission will be deleted when users delete the image.

  
  For example:
  When users specify '/etc/passwd' as locations value of an image user can get the file by image download.

  When locations of an image is set with 'file:///path/to/glance-
  api.conf' the conf will be deleted when users delete the image.

  How to recreate the bug:
  download files:
   - set show_multiple_locations True in glance-api.conf
   - create a new image
   - set locations of the image's property a path you want to get such as file:///etc/passwd.
   - download the image

  delete files:
   - set show_multiple_locations True in glance-api.conf
   - create a new image
   - set locations of the image's property a path you want to delete such as file:///path/to/glance-api.conf
   - delete the image

  I found this bug in 2014.2 (742c898956d655affa7351505c8a3a5c72881eae).

  What a big A RE RE!!
