Ubuntu Security Notice USN-1730-1

keystone vulnerabilities
==========================================================================

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

- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

Keystone could be made to crash or expose sensitive information over the
network.

Software Description:
- keystone: OpenStack identity service

Details:

Nathanael Burton discovered that Keystone did not properly verify disabled
users. An authenticated but disabled user would continue to have access
rights that were removed. (CVE-2013-0282)

Jonathan Murray discovered that Keystone would allow XML entity processing.
A remote unauthenticated attacker could exploit this to cause a denial of
service via resource exhaustion. Authenticated users could also use this to
view arbitrary files on the Keystone server. (CVE-2013-1664, CVE-2013-1665)

Update instructions:

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

Ubuntu 12.10:
python-keystone 2012.2.1-0ubuntu1.2

Ubuntu 12.04 LTS:
python-keystone 2012.1+stable~20120824-a16a0ab9-0ubuntu2.5

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