Updated openswan packages that fix one security issue are now available for
Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

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 discovered in the way Openswan's IKE
daemon processed IKEv2 payloads. A remote attacker could send specially
crafted IKEv2 payloads that, when processed, would lead to a denial of
service (daemon crash), possibly causing existing VPN connections to be
dropped. (CVE-2013-6466)

All openswan users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue.
