CVE-2014-0221 is an uncontrolled-recursion denial-of-service vulnerability in OpenSSL's dtls1_get_message_fragment function in d1_both.c. OpenSSL versions before 0.9.8za, 1.0.0m, and 1.0.1h improperly handle an invalid DTLS handshake hello message. A maliciously crafted handshake can cause recursive processing until the affected OpenSSL DTLS client crashes.
