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

Package:	wl
Issue Date:	Jul 23,2003   
Priority:	medium
Advisory ID: 	YDU-20030723-2


1. 	Topic:

	Updated wl packages are available.


2. 	Problem:
	
	"semi is a MIME library for GNU Emacs and XEmacs used by the wl mail package.

	A vulnerability in semi version 1.14.3 and earlier allows an attacker
	to overwrite arbitrary files with potentially arbitrary contents using the
	privileges of the user running Emacs and semi. The Common Vulnerabilities
	and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0440
	to this issue.

	Users of semi are advised to upgrade to these packages, which contain
	a backported patch correcting this issue."

	From Red Hat Advisory

	Semi is packaged as wl with yellowdog 3.0 .


3. 	Solution:

   	a) Updating via yum... 
	We suggest that you use the yum 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:

		yum update wl

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