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.
The following vulnerabilities have been found in the racoon daemon as
shipped with IPSec Tools:
<li>Neil Kettle reported that
racoon/isakmp_frag.c is prone to a null-pointer dereference
<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>
<impact type="normal">
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.
There is no known workaround at this time.
All IPSec Tools users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-firewall/ipsec-tools-0.7.2&quot;</code>
