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

  - The BN_GF2m_mod_inv function in crypto/bn/bn_gf2m.c in OpenSSL before 0.9.8s, 1.0.0 before 1.0.0e, 1.0.1     before 1.0.1n, and 1.0.2 before 1.0.2b does not properly handle ECParameters structures in which the curve     is over a malformed binary polynomial field, which allows remote attackers to cause a denial of service     (infinite loop) via a session that uses an Elliptic Curve algorithm, as demonstrated by an attack against     a server that supports client authentication. (CVE-2015-1788)

  - 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.
