How to fix?

Upgrade Debian:11 curl to version 7.74.0-1.3+deb11u5 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

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.
