  - Multiple denial of service flaws in the DTLS implementation (CVE-2009-1377, CVE-2009-1378,
  CVE-2009-1387)

  - Use-after-free vulnerability in the dtls1_retrieve_buffered_fragment function could cause a
  client accessing a malicious DTLS server to crash (CVE-2009-1379)

  - It was discovered that OpenSSL did not always check the return value of the bn_wexpand()
  function. An attacker able to trigger a memory allocation failure in that function could cause an
  application using the OpenSSL library to crash or, possibly, execute arbitrary code (CVE-2009-3245)

  - A Man-in-the-middle renegotiation attack (CVE-2009-3555)

  - A memory leak in the zlib_stateful_finish function in crypto/comp/c_zlib.c allows remote
  attackers to cause a denial of service via vectors that trigger incorrect calls to the
  CRYPTO_cleanup_all_ex_data function (CVE-2009-4355)");
