CVE-2013-6076 strongswan: denial of service when handling IKEv1 fragmentation payloads
A NULL pointer dereference flaw was discovered in strongSwan's IKE daemon, charon. An attacker could use this flaw to crash charon by sending a specially-crafted IKEv1 fragmentation payload.
strongSwan 5.1.1 corrects this flaw. A patch is provided for versions 5.0.2 and newer:

Created strongswan tracking bugs for this issue:
Affects: epel-6 [bug 1026154]

Looks like this issue is already fixed in the packages for Fedora testing so I did not file a tracking bug.
