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

Package:	ghostscript
Issue Date:	Jun 07,2003   
Priority:	medium
Advisory ID: 	YDU-20030607-1


1. 	Topic:

	Updated ghostscript packages are available.


2. 	Problem:
	
	"GNU Ghostscript is an interpreter for the PostScript language, and is often
	used when printing to printers that do not have their own built-in
	PostScript interpreter.

	A flaw in unpatched versions of Ghostscript before 7.07 allows malicious
	postscript files to execute arbitrary commands even with -dSAFER enabled. 

	Users of Ghostscript are advised to upgrade to these updated packages,
	which contain a backported patch and are not vulnerable 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

   	b) Updating manually...
	Download the updates below and then run the following rpm command.
   	(Please use a mirror site)
