Hey *,

the most recent openssl security update [0] breaks Tor. According to
our analysis so far, Tor isn't affected by the actual security issue, but
the patch as applied in openssl versions 1.0.0b and 0.9.8p causes
Tor to fail its handshake as a relay.

If you run a relay and have already upgraded your libssl, please
don't restart your relay unless you have to because it will otherwise
stop working. If you haven't upgraded, please verify whether any
other applications are affected and if not consider delaying the
upgrade.

So far I haven't been able to find a way to work around this issue
from inside Tor, but hopefully a fix can be developed soon.

Thanks for running relays!

Sebastian
