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

Package:	xloadimage	
Issue Date: 	July 25, 2001
Priority:	medium		
Advisory ID: 	YDU-20010725-11


1. 	Topic:

	The xloadimage package contains a possible
	overflow when called by a Netscape plugin.


2. 	Problem:

	"A buffer overflow existed in the faces reader for xloadimage. By making
	a specially constructed invalid faces file, and then having the server
	serve this file as a .tif file, arbitrary code could be executed on the
	client computer running Netscape."
	(from Red Hat's security 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 xloadimage 

   	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-2.0/ppc/RPMS/
		rpm -Fvh xloadimage-4.1-20.ppc.rpm
