FreeBSD : cURL -- ocsp status validation error (311e4b1c-f8ee-11e6-9940-b499baebfeaf)

Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

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.
