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
