Description of the vulnerability 

A client based on the OpenSSL library can create an encrypted session using elliptic curves (ECDH : elliptic curves and Diffie-Hellman).

However, a malicious server can negotiate an Anonymous ECDH ciphersuite, in order to trigger a denial of service in the OpenSSL client.

An attacker, who is located on a TLS server, can therefore use Anonymous ECDH, in order to trigger a denial of service in OpenSSL client applications.
