[tor-relays] Relay security, re: local network

[Joe]

Hi,

I'm planning to run a Tor relay on a spare computer at home. Security is 
a concern, and not only regarding the machine running the relay but also 
my other computers. Are there any (theoretical or otherwise) known 
attacks a person can perform on a running Tor relay to take remote 
control of it, and assuming the said person could pull that off, is it 
possible to extend this control to the other computers behind the same 
router? I am aware of possible DDOS attacks and other risks related to 
running an exit, but i am comfortable in taking these chances in my
environment.

I would run the relay on a yet-undecided-Linux distro, possibly Mint 
Debian or some flavor of Ubuntu which i am more familiar with, and use 
full-disk encryption with strong passwords. Are there any risks to my 
other computers worth consideration?

Thanks.
