Tor is an implementation of second generation Onion Routing, a
|
|
connection-oriented anonymizing communication service.

|
|
<p>
|
|
Some integer overflows exist when adding elements to the smartlists.
|
|
Non-printable characters received from the network are not properly
|
|
sanitised before being logged. There are additional unspecified bugs in
|
|
the directory server and in the internal circuits.
|
|
</p>

|
|
<impact type="normal">
|
|
<p>
|
|
The possible buffer overflow may allow a remote attacker to execute
|
|
arbitrary code on the server by sending large inputs. The other
|
|
vulnerabilities can lead to a Denial of Service, a lack of logged
|
|
information, or some information disclosure.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Tor users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose net-misc/tor</code>
|
|
</resolution>
