<description>
|
|
<p>
|
|
The Diffie-Hellman implementation of Tor fails to verify the
|
|
cryptographic strength of keys which are used during handshakes.

<impact type="low">
|
|
<p>
|
|
By setting up a malicious Tor server and enticing users to use
|
|
this server as first hop, a remote attacker could read and modify all
|
|
traffic of the user.

<workaround>
|

<p>
|

There is no known workaround at this time.

All Tor users should upgrade to the latest version:

<code>
|

# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/tor-0.1.0.14"</code>
