===============================================================================

CERT-NL (the SURFnet Computer Emergency Response Team) has received
information concerning a serious security problem in a software product
running on VAX/VMS.

The software concerned is "Calendar Manager",
produced by  Russell Information Sciences, Inc.
             115 Columbia Suite 100,
             Laguna Hills, CA, USA.
             Tel +1 714 362-4000  FAX +1 714 362 4040

The problems have become clear running Calendar Manager in combination
with VMS Version V5.5 and Pathworks for VMS S4.1C. However it is
firmly believed neither VMS nor Pathworks is the cause of the
problems. Presumably the security of any version of VMS and Pathworks
will be affected by Calendar Manager in the same way.

Description of the problem in all versions of Calendar Manager
preceding version V4.0-10 :

. Calendar Manager's startup procedure installs images with enhanced
  privileges. Installing images with privileges is a frequently used
  way to share information between users in a VMS environment.
. A method that exploits these installed images in an unintended
  manner has been discovered, giving rise to security problems.
. removing privileges from the installed images seriously restricts
  the functionality of the software.

Effectively this opens up a VAX/VMS system to methods that can obtain
full privileges for any user with access to Calendar Manager.

Recognizing the security issues in the Calendar Manager software,
Russell Information Sciences has responded by producing version V4.0-10.
Experienced users of Calendar Manager in The Netherlands have
confirmed that this version solves the problems exhibited in all
previous versions.

CERT-NL wishes to thank Willem Bast and Leo de Lange of PTT Research,
The Netherlands, for bringing this information to the attention of CERT-NL.
CERT-NL also thanks Russell Information Sciences, Inc. for their
cooperation in solving the security problems by producing the new version.
CERT-NL advises organisations running any version of Calendar Manager
up to V4.0-9 to obtain and install the latest version.

houdoe,

teun
