========================================================================== Ubuntu Security Notice USN-2061-1 December 19, 2013
keystone vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.10
Summary:
Keystone access controls could be circumvented via EC2-style tokens.
Software Description: - keystone: OpenStack identity service
Details:
Steven Hardy discovered that Keystone did not properly enforce trusts when using the ec2tokens API. An authenticated attacker could exploit this to retrieve a token not scoped to the trust and elevate privileges to the trustor's roles.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 13.10: python-keystone 1:2013.2-0ubuntu1.2
In general, a standard system update will make all the necessary changes.
