CVE-2014-9221 strongSwan vulnerability
Title: strongSwan vulnerability
Summary: strongSwan could be made to crash if it received specially
crafted network traffic.
Mike Daskalakis discovered that strongSwan incorrectly handled IKEv2
payloads that contained the Diffie-Hellman group 1025. A remote attacker
could use this issue to cause the IKE daemon to crash, resulting in a
denial of service.
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2014-9221 strongswan: denial-of-service vulnerability in libtls when processing crafted Key Exchange payload
One strongSwan users reported a denial-of-service vulnerability in
strongSwan. Affected are strongSwan versions 4.5.0 and newer, including
the latest 5.2.1.
The bug can be triggered by an IKEv2 Key Exchange (KE) payload that
contains the Diffie-Hellman (DH) group 1025. This identifier is from
the private-use range and only used internally by libtls for DH groups
with custom generator and prime (MODP_CUSTOM). As such the instantiated
method expects that these two values are passed to the constructor.
This is not the case when a DH object is created based on the group in
the KE payload. Therefore, an invalid pointer is dereferenced later,
which causes a segmentation fault. This
