Ubuntu Security Notice USN-1715-1
February 05, 2013

keystone vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10
- Ubuntu 12.04 LTS


Keystone could be made to fill server disks with error messages.

Software Description:
- keystone: OpenStack identity service


Dan Prince discovered that Keystone did not properly perform input
validation when handling certain error conditions. An unauthenticated user
could exploit this to cause a denial of service in Keystone API servers via
disk space exhaustion.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.10:
  python-keystone                 2012.2.1-0ubuntu1.1

Ubuntu 12.04 LTS:
  python-keystone                 2012.1+stable~20120824-a16a0ab9-0ubuntu2.4

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