  script_tag(name:"insight", value:"The following flaws exist:

  - CVE-2015-0206: A memory leak can occur in the dtls1_buffer_record function under certain
  conditions. In particular this could occur if an attacker sent repeated DTLS records with the same
  sequence number but for the next epoch. The memory leak could be exploited by an attacker in a
  Denial of Service attack through memory exhaustion.

  - CVE-2015-0205: An OpenSSL server will accept a DH certificate for client authentication without
  the certificate verify message. This effectively allows a client to authenticate without the use
  of a private key. This only affects servers which trust a client certificate authority which
  issues certificates containing DH keys: these are extremely rare and hardly ever encountered.");
