Scientific Linux Security Update : openswan on SL6.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

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.

A NULL pointer dereference flaw was found in the way Openswan's pluto
IKE daemon handled certain error conditions. A remote, unauthenticated
attacker could send a specially-crafted IKE packet that would crash
the pluto daemon. (CVE-2011-3380)

All users of openswan are advised to upgrade to these updated
packages, which contain a backported patch to correct this issue.
After installing this update, the ipsec service will be restarted
automatically.
