Subject: Security Update: [CSSA-2002-040.0] Linux: uudecode performs inadequate checks on user-specified output files



			SCO Security Advisory

Subject:		Linux: uudecode performs inadequate checks on user-specified output files
Advisory number: 	CSSA-2002-040.0
Issue date: 		2002 October 28
Cross reference:

1. Problem Description

	The uudecode utility would create an output file without checking
	to see if it was about to write to a symlink or a pipe. If a
	user uses uudecode to extract data into open shared directories,
	such as /tmp, this vulnerability could be used by a local attacker
	to overwrite files or lead to privilege escalation.

2. Vulnerable Supported Versions

	System				Package

	OpenLinux 3.1.1 Server		prior to sharutils-4.2.1-7MR.1.i386.rpm

	OpenLinux 3.1.1 Workstation	prior to sharutils-4.2.1-7MR.1.i386.rpm

	OpenLinux 3.1 Server		prior to sharutils-4.2.1-7MR.1.i386.rpm

	OpenLinux 3.1 Workstation	prior to sharutils-4.2.1-7MR.1.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.
