According to its self-reported version number, the remote pfSense install is affected by multiple vulnerabilities as stated in the referenced vendor advisories.

The remote host is affected by the vulnerability described in GLSA-201709-14 (cURL: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in cURL. Please review the       CVE identifiers referenced below for details.
  Impact :

    Remote attackers could cause a Denial of Service condition, obtain       sensitive information, or bypass intended restrictions for TLS sessions.
  Workaround :

    There is no known workaround at this time.

cURL security advisory :

libcurl would attempt to resume a TLS session even if the client certificate had changed. That is unacceptable since a server by specification is allowed to skip the client certificate check on resume, and may instead use the old identity which was established by the previous certificate (or no certificate).

libcurl supports by default the use of TLS session id/ticket to resume previous TLS sessions to speed up subsequent TLS handshakes. They are used when for any reason an existing TLS connection couldn't be kept alive to make the next handshake faster.

This flaw is a regression and identical to CVE-2016-5419 reported on August 3rd 2016, but affecting a different version range.

- fix switching off SSL session id when client cert is     used (CVE-2017-7468)

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that curl incorrectly handled client certificates when resuming a TLS session. A remote attacker could use this to hijack a previously authenticated connection.

The remote host is running Mac OS X 10.10.5, Mac OS X 10.11.6, or macOS 10.12.5 and is missing a security update. It is therefore, 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 out-of-bounds read errors exist in the libxml2     component due to improper handling of specially crafted     XML documents. An unauthenticated, remote attacker can     exploit these to disclose user information.
    (CVE-2017-7010, CVE-2017-7013)

  - Multiple memory corruption issues exist in the Intel     Graphics Driver component due to improper validation of     input. A local attacker can exploit these issues to     execute arbitrary code with elevated privileges.
