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

Package:	man	
Issue Date: 	July 25, 2001
Priority:	medium		
Advisory ID: 	YDU-20010725-5


1. 	Topic:


	The man package shipped with YDL 2.0
	contains a heap overflow.  Updated
	packages are available.


2. 	Problem:

	"A buffer size was calculated incorrectly in man.c.
	Since man is setgid man, users could gain gid man privileges."
	(from Red Hat's security 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 man 

   	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-2.0/ppc/RPMS/
		rpm -Fvh man-1.5i2-0.7x.ppc.rpm
