Package: dhcp3-client
Version: 3.1.1-6

A certain trojan exists which mimics the functionality of a DHCP server by pointing computers who receive this false DHCP information to an unsafe DNS server (in most cases 85.255.x.x). This DNS server helps spread infection on Windows machines. Although Linux is safe, it still gets the 85.255.x.x DNS server address which is blocked on most routers today, therefore blocking an internet connection. Please find attached a patch I have created for blocking this blacklisted DNS server. I hope it will evolve into a more advanced blacklisted DNS server blocker.

I am using Debian GNU/Linux 5.0 Lenny.
