"The version of Tenable Log Correlation Engine (LCE) installed on the
remote host is a version prior to 5.1.1. It is, therefore,
affected by multiple vulnerabilities:

  - A flaw exists in the bundled third-party component OpenSSL
    library's key handling during a TLS handshake that causes a
    denial of service vulnerability due to key handling during a TLS
    handshake. (CVE-2018-0732)

  - A flaw exists in the bundled third-party component OpenSSL
    library's RSA Key generation algorithm that allows a cache timing
    side channel attack to recover the private key. (CVE-2018-0737)");
