Tor is an implementation of second generation Onion Routing, a
connection-oriented anonymizing communication service.
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.
<impact type="normal">
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.
There is no known workaround at this time.
All Tor users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose net-misc/tor</code>
