CVE-2016-0757
Description
An authorization vulnerability in OpenStack Image service was discovered, which allowed image-status manipulation using locations. By removing the last location of an image, an authenticated user could change the status from 'active' to 'queue'. A malicious tenant could exploit this flaw to silently replace owned image data, regardless of its original creator or visibility settings. Only environments with show_multiple_locations set to true (not default) were affected.

Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
