keystone vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Summary:
Two security issues were fixed in OpenStack Keystone.
Software Description:
- keystone: OpenStack identity service
Details:
Dolph Mathews discovered that OpenStack Keystone did not properly
restrict to administrative users the ability to update users'
tenants. A remote attacker that can reach the administrative API can
use this to add any user to any tenant. (CVE-2012-3542)
Derek Higgins discovered that OpenStack Keystone did not properly
implement token expiration. A remote attacker could use this to
continue to access an account that has been disabled or has a changed
password. (CVE-2012-3426)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.04 LTS:
keystone 2012.1+stable~20120824-a16a0ab9-0ubuntu2.1
python-keystone 2012.1+stable~20120824-a16a0ab9-0ubuntu2.1
In general, a standard system update will make all the necessary changes.
