code execution.

Tor is an implementation of second generation Onion Routing, a
connection-oriented anonymizing communication service.
Tor contains a heap-based buffer overflow in the processing of user or
attacker supplied data. No additional information is available.
<impact type="high">
Successful exploitation of this vulnerability may allow an
unauthenticated remote attacker to execute arbitrary code with the
permissions of the Tor user, or to cause a Denial of Service.
There is no known workaround at this time.
All Tor users should upgrade to the latest stable version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-misc/tor-;</code>
