3. Description:

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

Two denial of service flaws were found in the ipsec-tools racoon daemon. It
was possible for a remote attacker to cause the racoon daemon to consume
all available memory. (CVE-2008-3651, CVE-2008-3652)

Users of ipsec-tools should upgrade to this updated package, which contains
backported patches that resolve these issues.

4. Solution:

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