<title>IPSec Tools: Denial of Service</title>
<synopsis>
Multiple errors in the IPSec Tools racoon daemon might allow remote
attackers to cause a Denial of Service.
</synopsis>

<bug>267135</bug>
<access>remote</access>
<affected>
<package name="net-firewall/ipsec-tools" auto="yes" arch="*">
<unaffected range="ge">0.7.2</unaffected>
<vulnerable range="lt">0.7.2</vulnerable>
</package>

<background>
<p>
The IPSec Tools are a port of KAME's IPsec utilities to the Linux-2.6
IPsec implementation. They include racoon, an Internet Key Exchange
daemon for automatically keying IPsec connections.
</p>
</background>
<description>
<p>
The following vulnerabilities have been found in the racoon daemon as
shipped with IPSec Tools:
</p>
<ul>
<li>Neil Kettle reported that
racoon/isakmp_frag.c is prone to a null-pointer dereference
(CVE-2009-1574).</li>
<li>Multiple memory leaks exist in (1) the
eay_check_x509sign() function in racoon/crypto_openssl.c and (2)
racoon/nattraversal.c (CVE-2009-1632).</li>
</ul>
</description>
<impact type="normal">
<p>
A remote attacker could send specially crafted fragmented ISAKMP
packets without a payload or exploit vectors related to X.509
certificate authentication and NAT traversal, possibly resulting in a
crash of the racoon daemon.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All IPSec Tools users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-firewall/ipsec-tools-0.7.2"</code>
</resolution>
