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

Package:	samba	
Issue Date: 	July 25, 2001
Priority:	high		
Advisory ID: 	YDU-20010725-8


1. 	Topic:

	New Samba packages are available that fix a
	security problem with remote clients giving special
	NetBIOS names to the server.


2. 	Problem:

	"The Samba configuration used in [Yellow Dog] Linux logs operations into
	[remotenetbiosname].log. By sending an invalid netbiosname, Samba could be
	fooled to write its log in unintended and inappropriate locations. This can
	be especially dangerous if combined with a symlink created by a local user."
	(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 samba
		yup update samba-client
		yup update samba-common 

   	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 samba-2.0.10-0.7.ppc.rpm
		rpm -Fvh samba-client-2.0.10-0.7.ppc.rpm
		rpm -Fvh samba-common-2.0.10-0.7.ppc.rpm
