		   Caldera Systems, Inc.  Security Advisory

Subject:		temp file problems in inn
Advisory number: 	CSSA-2001-001.0
Issue date: 		2001 January, 11
Cross reference:
______________________________________________________________________________


1. Problem Description

   INN uses a temporary directory for several operations. Those
   operations use it in a unsecure manner, which would allow an
   attacker to gain access to the 'news' user. Since INN is not
   supposed to work in a public temporary directory, please use
   the described workaround to change the temp directory to a
   news private one.


2. Vulnerable Versions

   System                       Package
   -----------------------------------------------------------
   OpenLinux Desktop 2.3        All released inn packages
   				

   OpenLinux eServer 2.3.1      All released inn packages
   and OpenLinux eBuilder

   OpenLinux eDesktop 2.4	All released inn packages


3. Solution

   Workaround:

   Edit /etc/news/inn.conf, change the line
	pathtmp:                /var/tmp
   to read
	pathtmp:                /var/run/news

   After this, restart INN by running as root:

	/etc/rc.d/init.d/news stop
	/etc/rc.d/init.d/news start


4. OpenLinux Desktop 2.3

   No fixed packages released, see workaround above.

5. OpenLinux eServer 2.3.1 and OpenLinux eBuilder for ECential 3.0

   No fixed packages released, see workaround above.

6. OpenLinux eDesktop 2.4

   No fixed packages released, see workaround above.
