Synopsis :

The remote Red Hat host is missing a security update.

Description :

Updated ipsec-tools packages that fix a denial of service flaw in
racoon are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the

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.
It was possible for a remote attacker, with knowledge of an existing
ipsec tunnel, to terminate the ipsec connection between two machines.
(CVE-2007-1841)

Users of ipsec-tools should upgrade to these updated packages, which
contain a backported patch that resolves this issue.
