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.
