How to fix?

Upgrade Centos:6 openswan to version 0:2.6.32-20.el6_4 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openswan package and not the openswan package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

Buffer overflow in the atodn function in Openswan before 2.6.39, when Opportunistic Encryption is enabled and an RSA key is being used, allows remote attackers to cause a denial of service (pluto IKE daemon crash) and possibly execute arbitrary code via crafted DNS TXT records. NOTE: this might be the same vulnerability as CVE-2013-2052 and CVE-2013-2054.
