  - A flaw exists in the Web Server component (Apache HTTP     Server) when handling whitespace patterns in User-Agent     headers. An authenticated, remote attacker can exploit     this, via a specially crafted User-Agent header, to     cause incorrect processing of sequences of requests,     resulting in incorrectly interpreting responses,     polluting the cache, or disclosing content from one     request to a second downstream user-agent.
    (CVE-2016-8743)

  - A NULL pointer dereference flaw exists within file     ssl/statem/statem_clnt.c when handling parameters for     the DHE or ECDHE key exchanges. An unauthenticated,     remote attacker can exploit this, via specially crafted     parameters, to cause a denial of service condition.
    (CVE-2017-3730)

  - A out-of-bounds read error exists exists in the Core     subcomponent, specifically in OpenSSL, when handling     packets using the CHACHA20/POLY1305 or RC4-MD5 ciphers.
    An unauthenticated, remote attacker can exploit this,     via specially crafted truncated packets, to cause a     denial of service condition. (CVE-2017-3731)

  - A carry propagating error exists in the x86_64     Montgomery squaring implementation that may cause the     BN_mod_exp() function to produce incorrect results. An     unauthenticated, remote attacker with sufficient     resources can exploit this to obtain sensitive     information regarding private keys. Note that this issue     is very similar to CVE-2015-3193. Moreover, the 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 cipher     suites. (CVE-2017-3732)

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

According to its banner, the version of OpenSSL on the remote host is prior to 1.1.0a and is affected by the following vulnerabilities :

 - A flaw exists in the 'ssl_parse_clienthello_tlsext()' function in 'ssl/t1_lib.c' that is triggered when handling overly large OCSP Status Request extensions from clients.  This may allow a remote attacker to exhaust available memory in a process linked against the library. (CVE-2016-6304)
 - A flaw exists in the 'SSL_peek()' function in 'ssl/record/rec_layer_s3.c' that is triggered during the handling of an empty record.  This may allow a remote attacker to cause SSL or TLS to hang in a process linked against the library. (CVE-2016-6305)
 - A flaw exists in the 'tls_get_message_header()' function in 'ssl/statem/statem_lib.c' that is triggered when handling TLS messages.  With a specially crafted request, a remote attacker can cause a process linked against the library to exhaust available memory. (CVE-2016-6307)
According to the vendor, this issue will only have a security impact if one of the following conditions are met :
 1) The application does not call 'SSL_free()' in a timely manner in the event that the connection fails,
 2) The application is working in a constrained environment where there is very little free memory, or
 3) The attacker initiates multiple connection attempts such that there are multiple connections in a state where memory has been allocated for the connection,  'SSL_free()' has not yet been called, and there is insufficient memory to service the multiple requests.
 - A flaw exists in the 'dtls1_preprocess_fragment()' function in 'ssl/statem/statem_dtls.c' that is triggered during the handling of excessively long DTLS messages.  This may allow a remote attacker to exhaust memory resources in a process linked against the library.  (CVE-2016-6308)

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

  - The ssl3_read_bytes function in record/rec_layer_s3.c in OpenSSL 1.1.0 before 1.1.0a allows remote     attackers to cause a denial of service (infinite loop) by triggering a zero-length record in an SSL_peek     call. (CVE-2016-6305)

  - Multiple memory leaks in t1_lib.c in OpenSSL before 1.0.1u, 1.0.2 before 1.0.2i, and 1.1.0 before 1.1.0a     allow remote attackers to cause a denial of service (memory consumption) via large OCSP Status Request     extensions. (CVE-2016-6304)

  - statem/statem_dtls.c in the DTLS implementation in OpenSSL 1.1.0 before 1.1.0a allocates memory before     checking for an excessive length, which might allow remote attackers to cause a denial of service (memory     consumption) via crafted DTLS messages. (CVE-2016-6308)

  - The state-machine implementation in OpenSSL 1.1.0 before 1.1.0a allocates memory before checking for an     excessive length, which might allow remote attackers to cause a denial of service (memory consumption) via     crafted TLS messages, related to statem/statem.c and statem/statem_lib.c. (CVE-2016-6307)

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