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

Package:	fetchmail	
Issue Date: 	July 25, 2001
Priority:	high		
Advisory ID: 	YDU-20010725-21


1. 	Topic:

	The fetchmail software has a buffer overflow.


2. 	Problem:

	A buffer overflow was discovered in all version of
	the fetchmail software prior to 5.8.6.  This can
	be exploited remotely and result in a root access
 	compromise if fetchmail is being run as root.


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 fetchmail 
		yup update fetchmailconf

   	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 fetchmail-5.8.14-1.ppc.rpm
		rpm -Fvh fetchmailconf-5.8.14-1.ppc.rpm
