Yellow Dog Linux Security Announcement
--------------------------------------

Package:	ghostscript		
Issue Date: 	June 06, 2002	
Priority:	medium		
Advisory ID: 	YDU-20020606-4


1. 	Topic:

	Updated ghostscript packages are available.


2. 	Problem:

	"Ghostscript is a program for displaying PostScript files or printing
	them to non-PostScript printers.

	An untrusted PostScript file can cause ghostscript to execute arbitrary
	commands due to insufficient checking. Since ghostscript is often used
	during the course of printing a document (and is run as user 'lp'), all
	users should install these fixed packages.

	The problem is fixed in the 6.53 source release of GNU Ghostscript, and the
	fix has been backported and applied to the packages referenced by this
	advisory.

	The Common Vulnerabilities and Exposures project (cve.mitre.org) has
	assigned the name CAN-2002-0363 to this issue."
	(from Red Hat Advisory)


3. 	Solution:

   	a) Updating via apt...
   	We suggest that you use the apt-get program to keep your
   	system up-to-date. The following command(s) will retrieve
   	and install the fixed version of this update onto your system:

		apt-get update
		apt-get install ghostscript printconf

   	b) Updating manually...
   	The update can also be retrieved manually from our ftp site
   	below along with the rpm command that should be used to install
   	the update.  (Please use a mirror site)

   		ftp://ftp.yellowdoglinux.com/pub/yellowdog/updates/yellowdog-2.2/ppc/
		rpm -Fvh ghostscript-6.51-16.2a.ppc.rpm
		rpm -Fvh printconf-0.3.61-4.1.ppc.rpm printconf-gui-0.3.61-4.1.ppc.rpm
