<p>Tor is an implementation of second generation Onion Routing, a
connection-oriented anonymizing communication service.
<p>Tor does not handle data correctly when specifically crafted data is
sent, and also fails to properly verify a descriptor provided by a hidden
service directory.
<impact type="normal">
<p>A remote attacker could cause a Denial of Service condition in both a
Tor client or a Tor server.
<p>There is no known workaround at this time.</p>
<p>All Tor users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-misc/tor-"
