Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200905-03
(IPSec Tools: Denial of Service)

The following vulnerabilities have been found in the racoon daemon as
shipped with IPSec Tools:
Neil Kettle reported that
racoon/isakmp_frag.c is prone to a null-pointer dereference
(CVE-2009-1574).
Multiple memory leaks exist in (1) the
eay_check_x509sign() function in racoon/crypto_openssl.c and (2)
racoon/nattraversal.c (CVE-2009-1632).

Impact :

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.

Workaround :

There is no known workaround at this time.
