<p>
IPsec-Tools is a port of KAME's implementation of the IPsec utilities.
It contains a collection of network monitoring tools, including racoon,
ping, and ping6.
</p>
</background>
<description>
<p>
The KAME IKE daemon racoon is used to authenticate peers during Phase 1
when using either preshared keys, GSS-API, or RSA signatures. When
using RSA signatures racoon validates the X.509 certificate but not the
RSA signature.
</p>
</description>
<impact type="normal">
<p>
By sending a valid and trusted X.509 certificate and any private key an
attacker could exploit this vulnerability to perform man-in-the-middle
attacks and initiate unauthorized connections.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version.
</p>
</workaround>
<resolution>
<p>
All IPsec-Tools users should upgrade to the latest stable version:
</p>
<code>
# emerge sync
# emerge -pv &quot;&gt;=net-firewall/ipsec-tools-0.3.3&quot;
# emerge &quot;&gt;=net-firewall/ipsec-tools-0.3.3&quot;</code>
</resolution>
