The version of OpenSSL installed on the remote host is prior to 1.1.0d. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.1.0d advisory.

  - There is a carry propagating bug in the x86_64 Montgomery squaring procedure in OpenSSL 1.0.2 before     1.0.2k and 1.1.0 before 1.1.0d. No EC algorithms are affected. Analysis suggests that attacks against RSA     and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks     against DH are considered just feasible (although very difficult) because most of the work necessary to     deduce information about a private key may be performed offline. The amount of resources required for such     an attack would be very significant and likely only accessible to a limited number of attackers. An     attacker would additionally need online access to an unpatched system using the target private key in a     scenario with persistent DH parameters and a private key that is shared between multiple clients. For     example this can occur by default in OpenSSL DHE based SSL/TLS ciphersuites. Note: This issue is very     similar to CVE-2015-3193 but must be treated as a separate problem. (CVE-2017-3732)

  - If an SSL/TLS server or client is running on a 32-bit host, and a specific cipher is being used, then a     truncated packet can cause that server or client to perform an out-of-bounds read, usually resulting in a     crash. For OpenSSL 1.1.0, the crash can be triggered when using CHACHA20/POLY1305; users should upgrade to     1.1.0d. For Openssl 1.0.2, the crash can be triggered when using RC4-MD5; users who have not disabled that     algorithm should update to 1.0.2k. (CVE-2017-3731)

  - In OpenSSL 1.1.0 before 1.1.0d, if a malicious server supplies bad parameters for a DHE or ECDHE key     exchange then this can result in the client attempting to dereference a NULL pointer leading to a client     crash. This could be exploited in a Denial of Service attack. (CVE-2017-3730)

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