PYSEC-2026-858 OpenStack Nova Router metadata queries are not restricted by tenant

Interaction error in OpenStack Nova and Neutron before Havana 2013.2.1 and icehouse-1 does not validate the instance ID of the tenant making a request, which allows remote tenants to obtain sensitive metadata by spoofing the device ID that is bound to a port, which is not properly handled by 1...

OpenStack Cinder, Glance, and Nova contain Uncontrolled Resource Consumption

The image parser in OpenStack Cinder prior to 7.0.2, and 8.0.0 and above, prior to 9.0.0; Glance prior to 14.00; and Nova prior to 12.0.4 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. This iss...
