critical security updates :

CVE-2009-1574 racoon/isakmp_frag.c in ipsec-tools before 0.7.2 allows
remote attackers to cause a denial of service (crash) via crafted
fragmented packets without a payload, which triggers a NULL pointer
dereference.

CVE-2009-1632 Multiple memory leaks in Ipsec-tools before 0.7.2 allow
remote attackers to cause a denial of service (memory consumption) via
vectors involving (1) signature verification during user
authentication with X.509 certificates, related to the
eay_check_x509sign function in src/racoon/crypto_openssl.c  and (2)
the NAT-Traversal (aka NAT-T) keepalive implementation, related to
src/racoon/nattraversal.c.

CVE-2008-3651 Memory leak in racoon/proposal.c in the racoon daemon in
ipsec-tools before 0.7.1 allows remote authenticated users to cause a
denial of service (memory consumption) via invalid proposals.

CVE-2008-3652 src/racoon/handler.c in racoon in ipsec-tools does not
remove an 'orphaned ph1' (phase 1) handle when it has been initiated
remotely, which allows remote attackers to cause a denial of service
(resource consumption).
