OpenStack Compute (Nova) Folsom, Grizzly, and Havana does not verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) by creating an image with a large virtual size that does not contain a large amount of data.

The LDAP backend in OpenStack Identity (Keystone) Grizzly and Havana, when removing a role on a tenant for a user who does not have that role, adds the role to the user, which allows local users to gain privileges.

OpenStack Compute (Nova) Folsom, Grizzly, and Havana, when usecowimages is set to False, does not verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) by transferring an image with a large virtual size that does not contain a large amount of data from Glance. NOTE: this issue is due to an incomplete fix for CVE-2013-2096.

OpenStack Compute (Nova) Folsom, Grizzly, and Havana does not properly verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) via a compressed QCOW2 image. NOTE: this issue is due to an incomplete fix for CVE-2013-2096.
