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

Package:	enscript	
Issue Date: 	January 27, 2002	
Priority:	medium		
Advisory ID: 	YDU-20020127-5


1. 	Topic:

	Updated enscript packages that fix insecure handling of
	temporary files are available.


2. 	Problem:

	GNU enscript is a program for converting ASCII files to PostScript(TM).
	When it creates temporary files, it does so with predictable filenames in
	a manner that would follow symbolic links. This could allow a local user
	to overwrite files written by the user running enscript, or read the
	contents of the temporary files.
	(from Red Hat advisory)


3. 	Solution:

   	a) Updating via yup...
   	We suggest that you use the Yellow Dog Update Program (yup)
   	to keep your system up-to-date. The following command(s) will
   	automatically retrieve and install the fixed version of
   	this update onto your system:

   		yup update enscript 
 

   	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-2.1/ppc/
		rpm -Fvh enscript-1.6.1-16.2.ppc.rpm
