The remote host is running a version of Mac OS X version 10.x prior to 10.12.6, and is affected by multiple vulnerabilities :

 - An overflow condition exists in the curl component in the 'dprintf_formatf()' function that is triggered when handling floating point conversion. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-9586)
 - A flaw exits in the curl component in the 'randit()' function within file lib/rand.c due to improper initialization of the 32-bit random value, which is used, for example, to generate Digest and NTLM authentication nonces, resulting in weaker cryptographic operations than expected. (CVE-2016-9594)
 - A flaw exists in the curl component in the 'allocate_conn()' function in lib/url.c when using the OCSP stapling feature for checking a X.509 certificate revocation status. The issue is triggered as the request option for OCSP stapling is not properly passed to the TLS library, resulting in no error being returned even when no proof of the validity of the certificate could be provided. A man-in-the-middle attacker can exploit this to provide a revoked certificate. (CVE-2017-2629)
 - A remote code execution vulnerability exists in the CoreAudio component due to improper validation of user-supplied input when handling movie files. An unauthenticated, remote attacker can exploit this, by convincing a user to play a specially crafted movie file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7008)
 - A memory corruption issue exists in the IOUSBFamily component due to improper validation of user-supplied input. A local attacker can exploit this, via a specially crafted application, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7009)

 - Multiple memory corruption issues exist in the kernel due to improper validation of input. A local attacker can exploit these issues to cause a denial of service condition or the execution of arbitrary code with kernel privileges. (CVE-2017-7023, CVE-2017-7025, CVE-2017-7027, CVE-2017-7069)
 - Multiple unspecified flaws exist in the kernel due to a failure to properly sanitize input. A local attacker can exploit these issues, via a specially crafted application, to disclose restricted memory contents. (CVE-2017-7028, CVE-2017-7029, CVE-2017-7067)
 - A flaw exists in the Foundation component due to improper validation of input. A unauthenticated, remote attacker can exploit this, by convincing a user to open specially crafted file, to execute arbitrary code. (CVE-2017-7031)
 - A memory corruption issue exists in the 'kext tools' component due to improper validation of input. A local attacker can exploit this to execute arbitrary code with elevated privileges. (CVE-2017-7032)
 - Multiple unspecified flaws exist in the Intel Graphics Driver component due to a failure to properly sanitize input. A local attacker can exploit these issues, via a specially crafted application, to disclose restricted memory contents. (CVE-2017-7036, CVE-2017-7045)
 - A memory corruption issue exists in the libxpc component due to improper validation of input. A local attacker can exploit this issue, via a specifically crafted application, to cause a denial of service condition or the execution of arbitrary code with system privileges. (CVE-2017-7047)

 - A certificate validation bypass vulnerability exists in the curl component due to the program attempting to resume TLS sessions even if the client certificate fails. An unauthenticated, remote attacker can exploit this to bypass validation mechanisms. (CVE-2017-7468)
 - A memory corruption issue exists in the Broadcom BCM43xx family Wi-Fi Chips component that allows an unauthenticated, remote attacker to execute arbitrary code. (CVE-2017-9417)


The cURL project reports :

SSL_VERIFYSTATUS ignored curl and libcurl support 'OCSP stapling', also known as the TLS Certificate Status Request extension (using the CURLOPT_SSL_VERIFYSTATUS option). When telling curl to use this feature, it uses that TLS extension to ask for a fresh proof of the server's certificate's validity. If the server doesn't support the extension, or fails to provide said proof, curl is expected to return an error. Due to a coding mistake, the code that checks for a test success or failure, ends up always thinking there's valid proof, even when there is none or if the server doesn't support the TLS extension in question. Contrary to how it used to function and contrary to how this feature is documented to work. This could lead to users not detecting when a server's certificate goes invalid or otherwise be mislead that the server is in a better shape than it is in reality.

The remote host is affected by the vulnerability described in GLSA-201703-04 (cURL: Certificate validation error)

    cURL and applications linked against libcurl support &ldquo;OCSP       stapling&rdquo;, also known as the TLS Certificate Status Request extension       (using the CURLOPT_SSL_VERIFYSTATUS option). When telling cURL to use       this feature, it uses that TLS extension to ask for a fresh proof of the       server&rsquo;s certificate&rsquo;s validity. If the server doesn&rsquo;t support the       extension, or fails to provide said proof, cURL is expected to return an       error.
      Due to a coding mistake, the code that checks for a test success or       failure, ends up always thinking there&rsquo;s valid proof, even when there       is none or if the server doesn&rsquo;t support the TLS extension in question.
  Impact :

    Due to the error, a user maybe does not detect when a server&rsquo;s       certificate goes invalid or otherwise be mislead that the server is in a       better shape than it is in reality.
  Workaround :

    There is no known workaround at this time.

The remote NewStart CGSL host, running version MAIN 6.02, has curl packages installed that are affected by multiple vulnerabilities:

  - The redirect implementation in curl and libcurl 5.11 through 7.19.3, when CURLOPT_FOLLOWLOCATION is     enabled, accepts arbitrary Location values, which might allow remote HTTP servers to (1) trigger arbitrary     requests to intranet servers, (2) read or overwrite arbitrary files via a redirect to a file: URL, or (3)     execute arbitrary commands via a redirect to an scp: URL. (CVE-2009-0037)

  - The Curl_input_negotiate function in http_negotiate.c in libcurl 7.10.6 through 7.21.6, as used in curl     and other products, always performs credential delegation during GSSAPI authentication, which allows     remote servers to impersonate clients via GSSAPI requests. (CVE-2011-2192)

  - curl and libcurl 7.2x before 7.24.0 do not properly consider special characters during extraction of a     pathname from a URL, which allows remote attackers to conduct data-injection attacks via a crafted URL, as     demonstrated by a CRLF injection attack on the (1) IMAP, (2) POP3, or (3) SMTP protocol. (CVE-2012-0036)

  - Stack-based buffer overflow in the Curl_sasl_create_digest_md5_message function in lib/curl_sasl.c in curl     and libcurl 7.26.0 through 7.28.1, when negotiating SASL DIGEST-MD5 authentication, allows remote     attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long string in     the realm parameter in a (1) POP3, (2) SMTP or (3) IMAP message. (CVE-2013-0249)

  - The tailMatch function in cookie.c in cURL and libcurl before 7.30.0 does not properly match the path     domain when sending cookies, which allows remote attackers to steal cookies via a matching suffix in the     domain of a URL. (CVE-2013-1944)

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