"The version of OpenSSL installed on the remote host is prior to 1.0.1t. It is, therefore, affected by multiple
vulnerabilities as referenced in the 1.0.1t advisory.

  - The X509_NAME_oneline function in crypto/x509/x509_obj.c in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h
    allows remote attackers to obtain sensitive information from process stack memory or cause a denial of
    service (buffer over-read) via crafted EBCDIC ASN.1 data. (CVE-2016-2176)

  - The asn1_d2i_read_bio function in crypto/asn1/a_d2i_fp.c in the ASN.1 BIO implementation in OpenSSL before
    1.0.1t and 1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (memory consumption)
    via a short invalid encoding. (CVE-2016-2109)

  - The AES-NI implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h does not consider memory
    allocation during a certain padding check, which allows remote attackers to obtain sensitive cleartext
    information via a padding-oracle attack against an AES CBC session. NOTE: this vulnerability exists
    because of an incorrect fix for CVE-2013-0169. (CVE-2016-2107)

  - Integer overflow in the EVP_EncryptUpdate function in crypto/evp/evp_enc.c in OpenSSL before 1.0.1t and
    1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (heap memory corruption) via a
    large amount of data. (CVE-2016-2106)

  - Integer overflow in the EVP_EncodeUpdate function in crypto/evp/encode.c in OpenSSL before 1.0.1t and
    1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (heap memory corruption) via a
    large amount of binary data. (CVE-2016-2105)

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