Caldera International, Inc. Security Advisory
Subject: Volution 1.0 security update
Advisory number: CSSA-2001-021.0
Issue date: 2001 June, 08
Cross reference:
______________________________________________________________________________
1. Problem Description
The Volution client and server components have been enhanced from
the currently shipping (English and International) components to
provide a higher level of security.
If you are using the Volution client that comes with OpenLinux 3.1,
you do not need to apply the client RPM listed here.
However, you will need to apply the server RPM.
Volution Client
One of the security enhancements made affects the way the Volution
client interacts with the Volution Computer Creation Daemon.
The new Volution client by default, WILL NOT use the Computer
Creation Daemon. To use the Computer Creation Daemon, edit the
/etc/opt/csm/csm.conf file and add a <useCCD/> entry.
Here is an example where the <useCCD/> entry has been added:
<?xml version='1.0' encoding='UTF-8'?>
<authentication>
<useCCD/>
<gateway>
<primaryGateway/>
<url>INSERT_YOUR_URL_HERE</url>
<authname>INSERT_YOUR_OBJECT_NAME_HERE</authname>
<password>INSERT_PASSWORD_HERE</password>
<objectname>INSERT_YOUR_OBJECT_NAME_HERE</objectname>
<cat name = "catSWRepository">
<location>INSERT_SWR_LOCATION_HERE</location>
</cat>
</gateway>
<authentication>
A Volution client with this csm.conf file change contacts the Volution
Computer Creation daemon and a new csm.conf file with the proper authname,
password, etc., is created.
The risk of having a <useCCD/> entry in the csm.conf file is that the
machine could be vulnerable to control by a rogue Volution server.
If a Volution client has <useCCD/> in the csm.conf file and it is unable
to authenticate to the LDAP directory server, it will attempt to contact
a Computer Creation Daemon which it finds using SLP.
If a rogue Volution system has been brought up inside your network,
the Volution client could communicate with the rogue Volution system.
If this happens, the rogue Volution system now has control of the client.
Volution Server
Security enhancements have also been made to the Volution server.
We recommend that you upgrade the Volution server components to
csm-server-1.0.8-47. The file /etc/opt/csm/csmccd.conf on the Volution
server is used as a template for new client csm.conf files that are created
as a result from a Volution client / Volution Computer Creation Daemon
communication. If you want Volution clients to continue to use the
Computer Creation Daemon, a <useCCD/> entry must be placed in the
csmccd.conf file.
Here is an example where the <useCCD/> entry has been added to the
csmccd.conf file:
<?xml version='1.0' encoding='UTF-8'?>
<csmwsc>
<authentication>
<useCCD/>
<gateway>
<primaryGateway/>
<url>LDAP://ldap.calderalabs.com:389</url>
<authname>INSERT_YOUR_OBJECT_NAME_HERE</authname>
<password>INSERT_YOUR_PASSWORD_HERE</password>
<objectname>INSERT_YOUR_OBJECT_NAME_HERE</objectname>
<cat name="catRPMRepository">
<location>ou=rpms,o=caldera</location>
</cat>
<cat name="catHWInventory"/>
<cat name="catSWInventory"/>
</gateway>
</authentication>
<workstationcreation>
<creationLocation>LOCATION_WORKSTATIONS_WILL_BE_CREATED</creationLocation>
<searchLocation>SEARCH_FOR_WORKSTATIONS_HERE_ON_UPDATES</searchLocation>
<searchLocation>AND_ALSO_SEARCH_HERE</searchLocation>
<searchLocation>AND_HERE (You can have as many as you need)</searchLocation>
</workstationcreation>
</csmwsc>
