Summary
CERTINFO never-ending busy-loop
Details

libcurl provides the CURLOPT_CERTINFO option to allow applications to request details to be returned about a TLS server's certificate chain.

Due to an erroneous function, a malicious server could make libcurl built with NSS get stuck in a never-ending busy-loop when trying to retrieve that information.
