The image parser in OpenStack Cinder 7.0.2 and 8.0.0 through 8.1.1; Glance before 11.0.1 and 12.0.0; and Nova before 12.0.4 and 13.0.0 does not properly limit qemu-img calls, which might allow attackers to cause a denial of service (memory and disk consumption) via a crafted disk image.

OpenStack Image Service (Glance) before 2015.1.3 (kilo) and 11.0.x before 11.0.2 (liberty), when show_multiple_locations is enabled, allow remote authenticated users to change image status and upload new image data by removing the last location of an image.
