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.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2014:0113 advisory.

    The openstack-keystone packages provide keystone, a Python implementation     of the OpenStack Identity service API, which provides Identity, Token,     Catalog, and Policy services.

    A flaw was discovered in the way the LDAP backend in keystone handled the     removal of a role. A user could unintentionally be granted a role if the     role being removed had not been previously granted to that user. Note that     only OpenStack Identity setups using an LDAP backend were affected.
    (CVE-2013-4477)

    All openstack-keystone users are advised to upgrade to these updated     packages, which contain a backported patch to correct this issue.

Brant Knudson discovered a logic error in the LDAP backend in Keystone where removing a role on a tenant for a user who does not have that role would instead add the role to the user. An authenticated user could use this to gain privileges. Ubuntu is not configured to use the LDAP Keystone backend by default.
