Important: ipsec-tools security update

An updated ipsec-tools package that fixes multiple security issues is now
available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

The ipsec-tools package is used in conjunction with the IPsec functionality
in the Linux kernel and includes racoon, an IKEv1 keying daemon.

A denial of service flaw was found in the ipsec-tools racoon daemon. An
unauthenticated, remote attacker could trigger a NULL pointer dereference
that could cause the racoon daemon to crash. (CVE-2009-1574)

Multiple memory leak flaws were found in the ipsec-tools racoon daemon. If
a remote attacker is able to make multiple connection attempts to the
racoon daemon, it was possible to cause the racoon daemon to consume all
available memory. (CVE-2009-1632)

Users of ipsec-tools should upgrade to this updated package, which contains
backported patches to correct these issues. Users must restart the racoon
daemon for this update to take effect.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
