OpenSSL suffers from a DTLS segmentation fault in dtls1_get_record, a DTLS memory leak in dtls1_buffer_record, an issue where no-ssl3 configuration sets method to NULL, ECDHE silently downgrades to ECDH [Client], RSA silently downgrades to EXPORT_RSA [Client], DH client certificates accepted without verification [Server], certificate fingerprints can be modified, and bignum squaring may produce incorrect results.
