  - Multiple race conditions in ssl/t1_lib.c, when multi-threading and internal caching are enabled on a TLS
  server related to the TLS server name extension and elliptic curve cryptography. (CVE-2010-3864)

  - Double free vulnerability in the ssl3_get_key_exchange function in the OpenSSL client (ssl/s3_clnt.c)
  when using ECDH. (CVE-2010-2939)");

  triggers a heap-based buffer overflow. (CVE-2010-3864)

  - allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary
  code via a crafted private key with an invalid prime. (CVE-2010-2939)");
