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

Package:	ethereal
Issue Date: 	January 13, 2002	
Priority:	medium	
Advisory ID: 	YDU-20030113-2


1. 	Topic:

	Updated ethereal packages are available.


2. 	Problem:

	"Ethereal is a package designed for monitoring network traffic on your
	system. Several security issues have been found in the Ethereal packages
	distributed with [Yellow Dog Linux 2.3].

	Multiple integer signedness errors in the BGP dissector in Ethereal
	0.9.7 and earlier allow remote attackers to cause a denial of service
	(infinite loop) via malformed messages. This problem was discovered by
	Silvio Cesare. CAN-2002-1355

	Ethereal 0.9.7 and earlier allows remote attackers to cause a denial
	of service (crash) and possibly execute arbitrary code via malformed
	packets to the LMP, PPP, or TDS dissectors. CAN-2002-1356

	Users of Ethereal should update to the erratum packages containing Ethereal
	version 0.9.8 which is 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 ethereal

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

		rpm -Fvh [filenames]
		ftp://ftp.yellowdoglinux.com/pub/yellowdog/updates/yellowdog-2.3/
			ppc/ethereal-0.9.8-0.73.0a.ppc.rpm

I wish to verify that each package has not been corrupted or tampered with,
examine the md5sum with the following command: rpm --checksig --nogpg filename
