RHBA-2013:1160 - openswan bug fix update

Synopsis

openswan bug fix update

Type/Severity

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

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