SSL: OpenSSL Anonymous ECDH Denial of Service
This signature detects attempts to exploit a known vulnerability against OpenSSL. The vulnerability is due to a NULL pointer dereference in processing handshake messages using anonymous ECDH ciphersuites. A remote, unauthenticated attacker could exploit this vulnerability by sending specially crafted messages to a target. Successful exploitation could lead to a denial of service condition.
Extended Description
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.
