Security Fix
- CVE-2013-6466
- 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.
All openswan users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.

Bug Fix
- BZ#1070358
- Previously, Openswan supported a NAT-T negotiation method which used a notification number that was assigned by the Internet Assigned Numbers Authority (IANA) for another option. This incorrect option was therefore removed. As a consequence, clients supporting non-RFC versions of NAT-T could not establish an Openswan connection. With this update, Openswan has been modified to fully ignore that option, and clients can send both the incorrect option and the draft or the RFC option to connect to Openswan successfully.
Users of openswan are advised to upgrade to these updated packages, which fix this bug.
