--------------------------------------

Package:	telnet	
Issue Date: 	August 10, 2001
Priority:	high		
Advisory ID: 	YDU-20010810-1


1. 	Topic:

	Updated telnet packages are available
	that fix security vulnerabilities.


2. 	Problem:

	Buffer overflows were recently discovered
	in the telnet package.  These overflows

3. 	Solution:

   	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 telnet 
		yup update telnet-server 

   	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 telnet-0.17-18.ppc.rpm
