Named Overlow Concern

[George Brown <jawjb bullnet co uk>]

I am running Linux 2.0.30 (Redhat 4.2) and have recently been hacked.

I have tightened up security but still feel vulnerable.

In running the program mscan which was kindly left on my system I get this.

	bullnet.co.uk: VULN: linux box vulnerable to named overflow.
	194.242.135.145: VULN: redhat linux box running imapd.

This is after upgrading to the versions as below.
	bind-4_9_7-0
	imap-4.1.final-0

Should I be concerned.
