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>
|
|
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>
