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

Package:	xinetd
Issue Date:	Jun 02,2003
Priority:	medium
Advisory ID: 	YDU-20030602-1


1. 	Topic:

	Updated xinetd packages are available.


2. 	Problem:
	
	"Xinetd is a 'master server' that is used to to accept service connection
	requests and start the appropriate servers.

	Because of a programming error, memory was allocated and never freed if a
	connection was refused for any reason. An attacker could exploit this flaw
	to crash the xinetd server, rendering all services it controls unavaliable.

	In addition, other flaws in xinetd could cause incorrect operation in
	certain unusual server configurations.

	All users of xinetd are advised to update to the packages listed in this
	erratum, which contain an upgrade to xinetd-2.3.11 and are not vulnerable
	to these issues."
	
	(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 xinetd

    	b) Updating manually...
	Download the updates below and then run the following rpm command.
    	(Please use a mirror site)

		rpm -Fvh [filenames]
		Yellow Dog Linux 3.0
		ftp://ftp.yellowdoglinux.com/pub/yellowdog/updates/yellowdog-3.0/
			ppc/xinetd-2.3.11-1.9.0.ppc.rpm
