The remote host is affected by the vulnerability described in GLSA-201703-04
(cURL: Certificate validation error)
cURL and applications linked against 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
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.
Due to the error, a user maybe does not detect when a server’s
certificate goes invalid or otherwise be mislead that the server is in a
better shape than it is in reality.
There is no known workaround at this time.
