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

Package:	mutt	
Issue Date: 	January 27, 2002	
Priority:	high		
Advisory ID: 	YDU-20020127-4


1. 	Topic:

	New mutt packages that fix an overflow in mutt's address parsing code are
	available. It is recommended that all mutt users update to the fixed
	packages.


2. 	Problem:

	An overflow exists in mutt's RFC822 address parser. A remote attacker
	could send a carefully crafted email message which when read by mutt would
	be able to overwrite arbitrary bytes in memory. The updated mutt-1.2.5.1
	release fixes the problem. Thanks go to Joost Pol for discovering the
	bug and the Mutt team for the fixed release.

	The Common Vulnerabilities and Exposures project (cve.mitre.org) has
	assigned the name CAN-2002-0001 to this issue
	(from Red Hat advisory)

3. 	Solution:

   	a) Updating via yup...
   	We suggest that you use the Yellow Dog Update Program (yup)
   	to keep your system up-to-date. The following command(s) will
   	automatically retrieve and install the fixed version of
   	this update onto your system:

   		yup update mutt 
 

   	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-2.1/ppc/
		rpm -Fvh mutt-1.2.5.1-1.ppc.rpm

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