========================================================================== Ubuntu Security Notice USN-2034-1 November 25, 2013
keystone vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.10 - Ubuntu 13.04 - Ubuntu 12.10
Summary:
Keystone would improperly remove roles when it was configured to use the LDAP backend.
Software Description: - keystone: OpenStack identity service
Details:
Brant Knudson discovered a logic error in the LDAP backend in Keystone where removing a role on a tenant for a user who does not have that role would instead add the role to the user. An authenticated user could use this to gain privileges. Ubuntu is not configured to use the LDAP Keystone backend by default.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 13.10: python-keystone 1:2013.2-0ubuntu1.1
Ubuntu 13.04: python-keystone 1:2013.1.4-0ubuntu1.1
Ubuntu 12.10: python-keystone 2012.2.4-0ubuntu3.3
In general, a standard system update will make all the necessary changes.
