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

Package:	fetchmail
Issue Date: 	December 27, 2002	
Priority:	medium
Advisory ID: 	YDU-20021227-4


1. 	Topic:

	Updated fetchmail packages are available.


2. 	Problem:

	"Fetchmail is a remote mail retrieval and forwarding utility intended for
	use over on-demand TCP/IP links such as SLIP and PPP connections. A bug
	has been found in the header parsing code in versions of Fetchmail prior
	to 6.2.0.

	This bug allows a remote attacker to crash Fetchmail and potentially
	execute arbitrary code by sending a carefully crafted email which is
	then parsed by Fetchmail.

	All users of Fetchmail are advised to upgrade to the errata packages
	containing a backported fix which corrects 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 fetchmail

   	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/fetchmail-5.9.0-21.7.3.ppc.rpm
			ppc/fetchmailconf-5.9.0-21.7.3.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
