The host is installed with OpenSSL before 0.9.8zb, 1.0.0 before 1.0.0n or 1.0.1 before 1.0.1i and is prone to denial of service vulnerability. A flaw is present in the application, which fails to handle a crafted handshake message in conjunction with a (1) anonymous DH or (2) anonymous ECDH ciphersuite. Successful exploitation allows remote DTLS servers to cause a denial of service.
