Ubuntu Security Notice USN-1564-1
September 13, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
OpenStack Keystone did not properly handle user role changes
- 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continue to access resources that have been revoked.
The problem can be corrected by updating your system to the following
Ubuntu 12.04 LTS:
In general, a standard system update will make all the necessary changes.
