It has been discovered that the random number generator in Debian's
|
|
openssl package is predictable. This is caused by an incorrect
|
|
Debian-specific change to the openssl package (CVE-2008-0166). As a
|
|
result, cryptographic key material may be guessable.
|
|
|
|
See Debian Security Advisory number 1571 (DSA-1571) for more information:
|
|
http://lists.debian.org/debian-security-announce/2008/msg00152.html
|
|
|
|
The Debian package for Tor has moved away the onion keys upon package
|
|
upgrade, and it will have moved away your identity key if it was created
|
|
in the affected timeframe. There is no sure way to automatically tell
|
|
if your key was created with an affected openssl library, so this move
|
|
is done unconditionally.
|
|
|
|
If you have restarted Tor since this change (and the package probably
|
|
did that for you already unless you configured your system differently)
|
|
then the Tor daemon already created new keys for itself and in all
|
|
likelyhood is already working just fine with new keys.
|
|
|
|
If you are absolutely certain that your identity key was created with
|
|
a non-affected version of openssl and for some reason you have to retain
|
|
the old identity, then you can move back the copy of secret_id_key to
|
|
/var/lib/tor/keys. Do not move back the onion keys, they were created
|
|
only recently since they are temporary keys with a lifetime of only a few
|
|
days anyway.
|
|
|

Sincerely,
|
