strongSwan before 5.1.2 allows remote attackers to cause a denial of service (NULL pointer dereference and IKE daemon crash) via a crafted ID_DER_ASN1_DN ID payload. Per: http://www.strongswan.org/blog/2014/05/05/strongswan-denial-of-service-vulnerability-%28cve-2014-2891%29.html
"Based on a crash report from one of our users we found that strongSwan versions before 5.1.2 are susceptible to a DoS vulnerability. Affected are strongSwan versions 4.3.3 and newer, up to 5.1.1. The latest release (5.1.3) is not affected."
