Removing telnet and finger?

[Rainer Gutkas]

As I just stumbled on my research for my diploma thesis over the 
following document:

http://www.giac.org/certified_professionals/practicals/gcux/0078.php

which suggests security issues for Laptops running debian systems and 
reccomends to remove telnet and finger because they are known to have 
securaty issues, I wondered if this is save within ubuntu.

If I wanna remove telnet (which I never use) Synaptic says I first gotta 
remove Ubuntu base
If I wanna remove finger Synaptic says i first gotta remove Gnome 
Nettool and ubuntu desktop.
Will this screw up my system, so I don't have this nice set up desktop 
enviroment anymore and probably all the base system? or are these just 
metapackages which can savely be removed?

Thanks for your suggestions,

Rainer
