CVE-2022-32221

When doing HTTP(S) transfers, libcurl might erroneously use the read
callback (CURLOPT_READFUNCTION) to ask for data to send, even when the
CURLOPT_POSTFIELDS option has been set, if the same handle previously was
used to issue a PUT request which used that callback. This flaw may
surprise the application and cause it to misbehave and either send off the
wrong data or use memory after free or similar in the subsequent POST
request. The problem exists in the logic for a reused handle when it is
changed from a PUT to a POST.
