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

Package:	bind		
Issue Date: 	June 06, 2002	
Priority:	high		
Advisory ID: 	YDU-20020606-6


1. 	Topic:

	Updated bind packages are available.


2. 	Problem:

	"BIND (Berkeley Internet Name Domain) is an implementation of the DNS
	(Domain Name System) protocols.  Versions of BIND 9 prior to 9.2.1 have a bug
	that causes certain requests to the BIND name server (named) to fail an
	internal consistency check, causing the name server to stop responding to
	requests.  This can be used by a remote attacker to cause a denial of
	service (DOS) attack against name servers.

	[Yellow Dog Linux 2.x] shipped with versions of BIND vulnerable to
	this issue.  All users of BIND are advised to upgrade to the errata
	packages containing BIND 9.2.1 which is 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 bind

   	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-2.2/ppc/
		rpm -Fvh bind-*9.2.1-0.7x.ppc.rpm
