CVE-2023-28322
Public on 2023-05-17
Modified on 2024-01-30
Description
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 second transfer.
The problem exists in the logic for a reused handle when it is (expected to be) changed from a PUT to a POST.
