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

  - 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)

  - The Server Gated Cryptography (SGC) implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not     properly handle handshake restarts, which allows remote attackers to cause a denial of service (CPU     consumption) via unspecified vectors. (CVE-2011-4619)

  - OpenSSL before 0.9.8s and 1.x before 1.0.0f, when RFC 3779 support is enabled, allows remote attackers to     cause a denial of service (assertion failure) via an X.509 certificate containing certificate-extension     data associated with (1) IP address blocks or (2) Autonomous System (AS) identifiers. (CVE-2011-4577)

  - The SSL 3.0 implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly initialize     data structures for block cipher padding, which might allow remote attackers to obtain sensitive     information by decrypting the padding data sent by an SSL peer. (CVE-2011-4576)

  - Double free vulnerability in OpenSSL 0.9.8 before 0.9.8s, when X509_V_FLAG_POLICY_CHECK is enabled, allows     remote attackers to have an unspecified impact by triggering failure of a policy check. (CVE-2011-4109)

  - The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f performs a MAC check only if     certain padding is valid, which makes it easier for remote attackers to recover plaintext via a padding     oracle attack. (CVE-2011-4108)

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