USN-2061-1: OpenStack Keystone vulnerability

19 December 2013

Keystone access controls could be circumvented via EC2-style tokens.




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

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