fail2ban needs updating ... DoS issue CVE-2006-6302

[Stuart Rowan <strr-backports-users@decisionsoft.com>]

As mentioned here:
http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6302

So I think it would be worth getting the current etch version into 
sarge-backports?

Thanks to all of you who work on backports.org, it really is an invaluable 
resource to so many of us.

Cheers,
Stu.
