  - A flaw exists in the tls_decrypt_ticket() function in     t1_lib.c due to improper handling of ticket HMAC     digests. An unauthenticated, remote attacker can exploit     this, via a ticket that is too short, to crash the     process, resulting in a denial of service.
    (CVE-2016-6302)

  - An integer overflow condition exists in the     MDC2_Update() function in mdc2dgst.c due to improper     validation of user-supplied input. An unauthenticated,     remote attacker can exploit this to cause a heap-based     buffer overflow, resulting in a denial of service     condition or possibly the execution of arbitrary code.
    (CVE-2016-6303)

  - A flaw exists in the ssl_parse_clienthello_tlsext()     function in t1_lib.c due to improper handling of overly     large OCSP Status Request extensions from clients. An     unauthenticated, remote attacker can exploit this, via     large OCSP Status Request extensions, to exhaust memory     resources, resulting in a denial of service condition.
    (CVE-2016-6304)

  - A flaw exists in the SSL_peek() function in     rec_layer_s3.c due to improper handling of empty     records. An unauthenticated, remote attacker can exploit     this, by triggering a zero-length record in an SSL_peek     call, to cause an infinite loop, resulting in a denial     of service condition. (CVE-2016-6305)

  - An out-of-bounds read error exists in the certificate     parser that allows an unauthenticated, remote attacker     to cause a denial of service via crafted certificate     operations. (CVE-2016-6306)

  - A denial of service vulnerability exists in the     state-machine implementation due to a failure to check     for an excessive length before allocating memory. An     unauthenticated, remote attacker can exploit this, via a     crafted TLS message, to exhaust memory resources.
    (CVE-2016-6307)

  - A denial of service vulnerability exists in the DTLS     implementation due to improper handling of excessively     long DTLS messages. An unauthenticated, remote attacker     can exploit this, via a crafted DTLS message, to exhaust     available memory resources. (CVE-2016-6308)

  - A remote code execution vulnerability exists in the     read_state_machine() function in statem.c due to     improper handling of messages larger than 16k. An     unauthenticated, remote attacker can exploit this, via a     specially crafted message, to cause a use-after-free     error, resulting in a denial of service condition or     possibly the execution of arbitrary code.
    (CVE-2016-6309)

  - A cross-site scripting (XSS) vulnerability exists within     the JQuery UI dialog() function due to improper     validation of input to the 'closeText' parameter before     returning it to users. An unauthenticated, remote     attacker can exploit this, via a specially crafted     request, to execute arbitrary script code in a user's     browser session. (CVE-2016-7103)

  - A denial of service vulnerability exists in x509_vfy.c     due to improper handling of certificate revocation lists     (CRLs). An unauthenticated, remote attacker can exploit     this, via a specially crafted CRL, to cause a NULL     pointer dereference, resulting in a crash of the     service. (CVE-2016-7052)

  - An unspecified cross-site scripting (XSS) vulnerability     exists in the web interface due to improper validation     of input before returning it to users. An     unauthenticated, remote attacker can exploit this, via a     specially crafted request, to execute arbitrary script     code in a user's browser session.

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

 - A flaw exists in the 'read_state_machine()' function of 'ssl/statem/statem.c'.  The issue is triggered when handling messages larger than ~ 16k.  With a specially crafted message, a remote attacker can trigger a use-after-free leading to a denial of service or potentially remote code execution. (CVE-2016-6309)
 - A flaw exists that is triggered when handling many consecutive 'SSL3_AL_WARNING' undefined alerts.  By continuously sending warning alerts, a remote attacker can cause a process linked against the library to exhaust available CPU resources and potentially stop responding. (CVE-2016-8610)

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

  - statem/statem.c in OpenSSL 1.1.0a does not consider memory-block movement after a realloc call, which     allows remote attackers to cause a denial of service (use-after-free) or possibly execute arbitrary code     via a crafted TLS session. (CVE-2016-6309)

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