Subject:		Linux: inn format string and insecure open vulnerabilities
Advisory number: 	CSSA-2002-038.0
Issue date: 		2002 October 24
Cross reference:
______________________________________________________________________________


1. Problem Description

	There are several format string coding bugs as well as unsecure
	open() calls in the inn program.


2. Vulnerable Supported Versions

	System				Package
	----------------------------------------------------------------------

	OpenLinux 3.1.1 Server		prior to inn-2.2.3-13.i386.rpm

	OpenLinux 3.1 Server		prior to inn-2.2.3-13.i386.rpm


3. Solution

	The proper solution is to install the latest packages. Many
	customers find it easier to use the Caldera System Updater, called
	cupdate (or kcupdate under the KDE environment), to update these
	packages rather than downloading and installing them by hand.
