What is CVE-2014-9221?

The strongSwan VPN software versions 4.5.x through 5.2.x prior to 5.2.1 are susceptible to a denial of service vulnerability. An attacker can exploit this flaw by sending a specially crafted IKEv2 Key Exchange message containing an invalid Diffie-Hellman group value, specifically group 1025. Successful exploitation may lead to service disruption as the software encounters an invalid pointer dereference during message processing.
