USN-1564-1: OpenStack Keystone vulnerability

13 September 2012

OpenStack Keystone did not properly handle user role changes

Releases

Packages

Details

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continue to access resources that have been revoked.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

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