"The version of OpenSSL installed on the remote host is prior to 0.9.8zg. It is, therefore, affected by multiple
vulnerabilities as referenced in the 0.9.8zg advisory.

  - The do_free_upto function in crypto/cms/cms_smime.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1
    before 1.0.1n, and 1.0.2 before 1.0.2b allows remote attackers to cause a denial of service (infinite
    loop) via vectors that trigger a NULL value of a BIO data structure, as demonstrated by an unrecognized
    X.660 OID for a hash function. (CVE-2015-1792)

  - The PKCS7_dataDecodefunction in crypto/pkcs7/pk7_doit.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s,
    1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b allows remote attackers to cause a denial of service (NULL
    pointer dereference and application crash) via a PKCS#7 blob that uses ASN.1 encoding and lacks inner
    EncryptedContent data. (CVE-2015-1790)

  - The X509_cmp_time function in crypto/x509/x509_vfy.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1
    before 1.0.1n, and 1.0.2 before 1.0.2b allows remote attackers to cause a denial of service (out-of-bounds
    read and application crash) via a crafted length field in ASN1_TIME data, as demonstrated by an attack
    against a server that supports client authentication with a custom verification callback. (CVE-2015-1789)

  - Race condition in the ssl3_get_new_session_ticket function in ssl/s3_clnt.c in OpenSSL before 0.9.8zg,
    1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b, when used for a multi-threaded client,
    allows remote attackers to cause a denial of service (double free and application crash) or possibly have
    unspecified other impact by providing a NewSessionTicket during an attempt to reuse a ticket that had been
    obtained earlier. (CVE-2015-1791)

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