RHBA-2013:1160 - Bug Fix Advisory

Topic

Updated openswan packages that fix one bug are now available for Red Hat
Enterprise Linux 6 Extended Update Support.

Description

Openswan is a free implementation of Internet Protocol Security (IPsec) and
Internet Key Exchange (IKE). IPsec uses strong cryptography to provide both
authentication and encryption services. These services allow you to build secure
tunnels through untrusted networks.

This update fixes the following bug:

• The openswan package for Internet Protocol Security (IPsec) contains two

diagnostic commands, "ipsec barf" and "ipsec look", that can cause the iptables
kernel modules for NAT and IP connection tracking to be loaded. On very busy
systems, loading such kernel modules can result in severely degraded performance
or lead to a crash when the kernel runs out of resources. With this update, the
diagnostic commands do not cause loading of the NAT and IP connection tracking
modules. This update does not affect systems that already use IP connection
tracking or NAT as the iptables and ip6tables services will already have loaded
these kernel modules. (BZ#983451)

Users of openswan are advised to upgrade to these updated packages, which fix
this bug.

Solution

to your system have been applied.
