Re: [tor-relays] Long-term effect of Heartbleed on Tor

2014-04-10 Thread Felix Büdenhölzer

 *However*, if there's a way to specify the data it sends back, that
 wouldn't be a problem (I'm no legal specialist though). I have not yet
 tested my theory, but sending a few extra bytes in the heartbeat
 message (and of course incrementing 'length' in the 'ssl3_record_st'
 struct) should do that. It would allow causing the server to return
 data the client sent. If it's not sent back, the server isn't
 vulnerable. No random memory is read as the server did in fact
 allocate the memory, it's simply not supposed to use it.
If I get you in the right way I think this is what you are asking for:
https://github.com/FiloSottile/Heartbleed
This guy is sending a string in and reads it back.

Re: [tor-relays] Relay, bridge, and family members

2014-01-16 Thread Felix Büdenhölzer
I am unsure right now why exactly a bridge
should not be listed respectively list a family, other than you leak the
existence of the bridge(s).



Actually this is the exact and only reason. From the DOC:

Do not list any bridge relay as it would compromise its concealment



So, dont list those friendly bridges in your MyFamily settings.

Same thing for me. I have asked the donation guys by writing a short
mail to donati...@torproject.org and they replied with the link to the
shirt supplier.

Re: [tor-relays] Tor Relay Operators Meeting at 30c3 Chaos Communication Congress

2013-12-02 Thread Felix Büdenhölzer
FYI:
Yoriz informed me about an issue with my mail signing (bad signature).
It turns out that there was a problem with the mail encoding. So, no
need for increased paranoia :-)
