Ubuntu Security Notice USN-1564-1
September 13, 2012

keystone vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS


OpenStack Keystone did not properly handle user role changes

Software Description:
- keystone: OpenStack identity service


Dolph Mathews discovered that when roles are granted and revoked to
users in Keystone, pre-existing tokens were not updated or invalidated
to take the new roles into account. An attacker could use this to
continue to access resources that have been revoked.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
  keystone                        2012.1+stable~20120824-a16a0ab9-0ubuntu2.2
  python-keystone                 2012.1+stable~20120824-a16a0ab9-0ubuntu2.2

In general, a standard system update will make all the necessary changes.
