The version of OpenSSL installed on the remote host is prior to 1.0.0p. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.0p advisory.

  - Memory leak in the dtls1_buffer_record function in d1_pkt.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1     before 1.0.1k allows remote attackers to cause a denial of service (memory consumption) by sending many     duplicate records for the next epoch, leading to failure of replay detection. (CVE-2015-0206)

  - The ssl3_get_cert_verify function in s3_srvr.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k     accepts client authentication with a Diffie-Hellman (DH) certificate without requiring a CertificateVerify     message, which allows remote attackers to obtain access without knowledge of a private key via crafted TLS     Handshake Protocol traffic to a server that recognizes a Certification Authority with DH support.
    (CVE-2015-0205)

  - The BN_sqr implementation in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not     properly calculate the square of a BIGNUM value, which might make it easier for remote attackers to defeat     cryptographic protection mechanisms via unspecified vectors, related to crypto/bn/asm/mips.pl,     crypto/bn/asm/x86_64-gcc.c, and crypto/bn/bn_asm.c. (CVE-2014-3570)

  - The ssl3_get_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1     before 1.0.1k allows remote SSL servers to conduct RSA-to-EXPORT_RSA downgrade attacks and facilitate     brute-force decryption by offering a weak ephemeral RSA key in a noncompliant role, related to the FREAK     issue. NOTE: the scope of this CVE is only client code based on OpenSSL, not EXPORT_RSA issues associated     with servers or other TLS implementations. (CVE-2015-0204)

  - OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not enforce certain constraints     on certificate data, which allows remote attackers to defeat a fingerprint-based certificate-blacklist     protection mechanism by including crafted data within a certificate's unsigned portion, related to     crypto/asn1/a_verify.c, crypto/dsa/dsa_asn1.c, crypto/ecdsa/ecs_vrf.c, and crypto/x509/x_all.c.
    (CVE-2014-8275)

  - The ssl3_get_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1     before 1.0.1k allows remote SSL servers to conduct ECDHE-to-ECDH downgrade attacks and trigger a loss of     forward secrecy by omitting the ServerKeyExchange message. (CVE-2014-3572)

  - OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote attackers to cause a     denial of service (NULL pointer dereference and application crash) via a crafted DTLS message that is     processed with a different read operation for the handshake header than for the handshake body, related to     the dtls1_get_record function in d1_pkt.c and the ssl3_read_n function in s3_pkt.c. (CVE-2014-3571)

  - The ssl23_get_client_hello function in s23_srvr.c in OpenSSL 0.9.8zc, 1.0.0o, and 1.0.1j does not properly     handle attempts to use unsupported protocols, which allows remote attackers to cause a denial of service     (NULL pointer dereference and daemon crash) via an unexpected handshake, as demonstrated by an SSLv3     handshake to a no-ssl3 application with certain error handling. NOTE: this issue became relevant after the     CVE-2014-3568 fix. (CVE-2014-3569)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
