This vulnerability does not affect current versions of OpenSSL. It existed in previous OpenSSL versions and was fixed in June 2014. If a DTLS peer receives application data between the ChangeCipherSpec and Finished messages, buffering of such data may cause an invalid free, resulting in a segmentation fault or potentially, memory corruption.

Found by Praveen Kariyanahalli, and subsequently by Ivan Fratric and Felix Groebert (Google).
