The ssl3_send_client_key_exchange function in s3_clnt.c in OpenSSL before
0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h, when an anonymous
ECDH cipher suite is used, allows remote attackers to cause a denial of
service (NULL pointer dereference and client crash) by triggering a NULL
certificate value.
