"The version of OpenSSL installed on the remote host is prior to 1.0.2e. It is, therefore, affected by multiple
vulnerabilities as referenced in the 1.0.2e advisory.

  - The ASN1_TFLG_COMBINE implementation in crypto/asn1/tasn_dec.c in OpenSSL before 0.9.8zh, 1.0.0 before
    1.0.0t, 1.0.1 before 1.0.1q, and 1.0.2 before 1.0.2e mishandles errors caused by malformed X509_ATTRIBUTE
    data, which allows remote attackers to obtain sensitive information from process memory by triggering a
    decoding failure in a PKCS#7 or CMS application. (CVE-2015-3195)

  - crypto/rsa/rsa_ameth.c in OpenSSL 1.0.1 before 1.0.1q and 1.0.2 before 1.0.2e allows remote attackers to
    cause a denial of service (NULL pointer dereference and application crash) via an RSA PSS ASN.1 signature
    that lacks a mask generation function parameter. (CVE-2015-3194)

  - The Montgomery squaring implementation in crypto/bn/asm/x86_64-mont5.pl in OpenSSL 1.0.2 before 1.0.2e on
    the x86_64 platform, as used by the BN_mod_exp function, mishandles carry propagation and produces
    incorrect output, which makes it easier for remote attackers to obtain sensitive private-key information
    via an attack against use of a (1) Diffie-Hellman (DH) or (2) Diffie-Hellman Ephemeral (DHE) ciphersuite.
    (CVE-2015-3193)

  - The ssl3_get_key_exchange function in ssl/s3_clnt.c in OpenSSL 1.0.2 before 1.0.2e allows remote servers
    to cause a denial of service (segmentation fault) via a zero p value in an anonymous Diffie-Hellman (DH)
    ServerKeyExchange message. (CVE-2015-1794)

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