Multiple vulnerabilities have been discovered in Openswan:
</p>
<ul>
<li>Gerd v. Egidy reported a NULL pointer dereference in the Dead Peer
Detection of the pluto IKE daemon as included in Openswan
(CVE-2009-0790).</li>
<li>The Orange Labs vulnerability research team
discovered multiple vulnerabilities in the ASN.1 parser
(CVE-2009-2185).</li>
</ul>
</description>
<impact type="normal">
<p>
A remote attacker could exploit these vulnerabilities by sending
specially crafted R_U_THERE or R_U_THERE_ACK packets, or a specially
crafted X.509 certificate containing a malicious Relative Distinguished
Name (RDN), UTCTIME string or GENERALIZEDTIME string to cause a Denial
of Service of the pluto IKE daemon.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Openswan users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-misc/openswan-2.4.15&quot;</code>
</resolution>
