	Somebody at OpenBSD discovered a possible root exploit in the ISC DHCP
	client.  This exploit is present in all versions of the ISC DHCP
	client prior to 2.0pl1 and 3.0b1pl14, which I just released this
	evening.  Anybody who is using versions of the ISC DHCP client other
	than these is strongly urged to upgrade.  I would appreciate it if the
	OpenBSD people would take a look at the new version to see if they
	believe it is a complete fix, and let me know if it isn't.  In any
	case, thanks for catching the error!  I'm sorry I'm being so vague
	about how this got found, but I don't have time to read bugtraq
	anymore, so I was notified roughly fourth-hand.
	
	The ISC DHCP distribution is available at ftp://ftp.isc.org/isc/DHCP,
	and anonymous CVS at http://www.isc.org/products/DHCP/anoncvs.html.
	The head of the tree in anonymous CVS also contains the fix.
