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) (CVE-2016-5419).

In libcurl before 7.50.1, when using a client certificate for a connection
that was then put into the connection pool, that connection could then
wrongly get reused in a subsequent request to that same server. This
mistakenly using the wrong connection could lead to applications sending
requests to the wrong realms of the server using authentication that it
wasn't supposed to have for those operations (CVE-2016-5420).

libcurl before 7.50.1 is vulnerable to a use-after-free flaw in
curl_easy_perform() (CVE-2016-5421).");
