			SCO Security Advisory

Advisory number: 	CSSA-2003-021.0
Issue date: 		2003 May 13
Cross reference:
______________________________________________________________________________


1. Problem Description

	mgetty will overflow an internal buffer if the caller name
	reported by the modem is too long.

	The faxspool spooling directory used for outgoing faxes was
	world-writable.


2. Vulnerable Supported Versions

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

	OpenLinux 3.1.1 Server		prior to mgetty-1.1.22_Aug17-13.i386.rpm

	OpenLinux 3.1.1 Workstation	prior to mgetty-1.1.22_Aug17-13.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.
